recognition of demonic/extra-planar entity presence
So if you wonder if there is a demonic/extra-planar entity affecting your daily activity.., and you aren't puking up pea soup, your head isn't rotating, you aren't climbing the walls crab style.... yet you are wondering if there is external influences in your activities... is there a litmus test... some way to determine if it is mundane or... other?

"Unexplainable foul odors that appear from nowhere and the source cannot be found
If you hear knocking or banging on the walls and the source cannot be found - bangings will often come in 3's - as a mocking of the Trinity. Banging noises in the walls can be Poltergeist activity and/or signs of electrical problems. Always search for logical explanations first.
Pay very close to how animals in the home react - are they frightened and alarmed to something that you cannot see but hear? When animals are in the presence of a true demonic entity, they are fully aware of its presence. Depending on the breed of the dog, there is a “flight or fight” instinct that will occur. For example, a German Shepherd will begin to become quite aggressive and the instincts of the animal will be to immediately go into the “fight” mode to protect the family. Snarling, snapping, and excessive salivating could occur during the fight mode. Even though the family may see nothing, the animal is clearly displaying an aggressive response at an entity that poses a direct threat to the animal or family.
Many people have claimed to have seen dark shadowy figures but this can also be human entities as well
There will be an overwhelming oppressive feeling - people feeling sick to their stomach while going to the infested room. Keep in mind that this could also be electro currents causing havoc as well.
You begin to get a sense of dread and your 6th sense tells you that something is not right
Heavy objects will move by themselves and these objects usually have a target - you or guests
Religious articles are destroyed or they may completely disappear and pay attention to any
Growling or scratching noises that can be clearly heard but the source cannot be verified."

Re: recognition of demonic/extra-planar entity presence
Thats one way you could look at it, if you have extremely xian beliefs. From what i am hearing, we are judging all demons as maleficent entities that want to harm a a person or those close to them? Im just trying to understand what train of thought you two are coming from. If the last post had any credibility at all, then would there even be Daemonolatry at all? I know several Daemonolators, and they have never described any putrid odor hanging around (in fact, it seems demons enjoy pleasant smelling incenses) due to the presents of their familiars or other demons they may be working with. Sounds like someone has watched The Conjuring one time too many.

Re: recognition of demonic/extra-planar entity presence
I actually believe that. But it is almost the same thing as judging Lord Satan from the biased musings of the xian bible. Or judging the xian god or the nazarene by looking for info in LaVeys publications. You have to consider the source, and buying in to xian theology in regards to another theistic belief is silly, as xians are well known for using fear propaganda to keep others away from all other beliefs other than their own. I have read tons of books and sites that describe Satan as some type of "lowly fallen angel" that slithers around on his belly, trying to make humans "sin". This is not the case. Nor are demons all evil entities that torment and tempt humans. Demons are very knowledgeable and helpful when approached properly. Meaning invoked with respect, as opposed to the rude and offensive evocation techniques that most Demonologists describe. There are always two sides to every coin. Both should be scrutinized thoroughly before a proper opinion is formed. Just sayin.

Re: recognition of demonic/extra-planar entity presence
I would say that if there are a lot of accidents or things generally just going wrong, there might be something around that is not healthy for you, be it demonic or whatever. In my experience these things have been attached to people more often than places.

BUT, the original poster asked for demonic influence in your daily life.
I highly doubt any of the prince and dukes of hell would be roaming the earth messing with people just for shits and giggles.
If a demon has forced it's way into your life and is affecting it. You can't use the same logic as how a demon acts when you have summoned/conjured it.

Re: recognition of demonic/extra-planar entity presence
Very true, but, if you have ever worked with demons or know someone that does regularly, you will know that they wouldn't do such a thing without a good reason (like being requested to by a Demonolator, and thats about the only reason i can fathom). Using that line of thought.......has the OP pissed off any Demonolators? Or maybe opened himself to entities like BA or sludge entities? Are we practicing invocation or evocation in any form? These are all good questions, and the answers could help us solve the dilemma.

Re: recognition of demonic/extra-planar entity presence
Well if we are allowed to go off topic.
It's not demons.
Trust me, if it was demons you would know. Small disturbances in your daily life usually comes from small sources.

Re: recognition of demonic/extra-planar entity presence
Not that its my call, but I'd say that is right on-topic. The key to dealing with an influencing entity is to know what type of entity you are dealing with. And i totally agree.......not a demon.

No, as far as my original post, I was joking about the above. It was in contrast to the subtle answers I would be expecting.manofsands wrote:.., and you aren't puking up pea soup, your head isn't rotating, you aren't climbing the walls crab style.... ?
I have not been messing in any kind of evocation/invocation. I do know a couple people who thought they have been harassed by 'something' for a long time ( though I haven't heard as much from them in years). The only demonologists I could have pissed off are in this forum. I state all of this just so you know my level of 'exposure'.
I don't really even get the feeling any of this is the case.I'm mainly just wondering two things... If you haven't actively summoned a demon/extraplanar entity, but are wondering if there are any 'hanging out'...
1) are there reoccurring signs to hint at its presence..
2) is there an actual litmus test... I don't know, placing a banana on a pentagram and it spoils in 6 min (again, tounge in cheek,.. just a bad example)

If it is "normal" to be effected by entities in the day to day even if we don't notice or if it is as hard for them to affect us as us affect them.Desecrated wrote:If you haven't built an airplane in your apartment, how do you know it isn't there?

I can understand that, and as said by others, there are many entities lumped in with demons. And those of a sort from such a place, I can see can only be about if summoned. But by context of other posts/threads I get that many are here and interact with us more regularly.Desecrated wrote:

I'm still open to other views of the original question,... but I'll continue on the present conversation as well.
Question: Demons and other extraplanar entities,... once summoned... can they, thru improper 'handling' or ritual be left on 'this side' or is it more like Skypeing and the worse you do is get a bad or no connection?

Re: recognition of demonic/extra-planar entity presence
Entities, spirits, ghosts, demons and tigers and bears, oh my.
Sure, sometimes, they're there because we called them (or someone who lived there previously did.) Sometimes, they belong to the building or the land or whatever it is that they're tied to. Sometimes, they blow their brains out and get stuck where they did it or have a horrific car wreck and haunt stretches of road.
A lot of times, these things reside in these places long before we arrive there and notice them. Depending on the type of 'thing', level of power, type of personality, etc that it has it can like to be in your face and claw you to bloody shreds or just whisper bad ideas in your ear until you think they're your own.
Day or night - doesn't usually matter to them. Night is easier for us because our physical senses are less engaged. Do you really think that a ghost gives a shit if there's a floodlight or a nightvision camera? I've found with the dead that it's usually more a specific time than light or dark outside. On the flip side of that - if you don't have decent protections in place - it is easier to screw with someone while they're sleeping and not otherwise occupied with the physical world.
Desecrated - do those 'monkeys' happen to look like the gargoyles on the medieval churches?

Re: recognition of demonic/extra-planar entity presence
Hey sweetie! It's been a super hectic holiday season for me this year with way too many thousands of miles in the car. I need a vacation to recover from my Xmas vacation. Some pretty amazing things happened along the way. It truly is a magical season.
Onto your questions...
I'm also not quite sure what you mean by extraplanar entity. Can you clarify on that for a more specific reply, please?
You don't need to summon a demon or demonic like entity to have them hanging around. There's lots of reasons they could be there. One thing I've recently learned is that a lot of malicious entities really aren't. They're misunderstood and abused in enemy territory. It's no wonder that they act out in the ways that they do.
Recurring signs...
odd smells, behaving in strange ways - especially with frustration and anger that's not actually your own, items disappearing and reappearing in different places, noises, knockings, if it's strong enough it can mess with you physically. (On that note - don't discredit the power that an angry and confused ghost can have, especially to those that are sensitive to it - and can, a lot of times, be thought to be demonic when they're really not), hot and cold spots, feelings of utter dread in certain places, lights and electronics behaving abnormally (the key word being behaving - inanimate objects don't usually have a behavior). emotional outbursts. In really bad cases - scratches and burn marks, doors opening and closing, shit flying across the room - these things really do happen.
But mostly, if you think of the personality changes shown in the Amityville Horror movies - shit like that happens, too.
Litmus test...
That's going to depend on what it is that you're dealing with. The only way I know is to bring in someone that knows what they're doing and even that's not always 100% The smarter entities do know how to hide.
Is there a reason for these questions or is it mere curiosity?
Onto your questions...
Are you speaking about demon and/or demon like entities alone or any manner of spiritual critter? The reoccurring signs are different depending on what you're dealing with - if there are any. If we're talking about something with that much power than yeah - there almost always are.I'm mainly just wondering two things...

(On that note - don't discredit the power that an angry and confused ghost can have, especially to those that are sensitive to it - and can, a lot of times, be thought to be demonic when they're really not), hot and cold spots, feelings of utter dread in certain places, lights and electronics behaving abnormally (the key word being behaving - inanimate objects don't usually have a behavior). emotional outbursts. In really bad cases - scratches and burn marks, doors opening and closing, shit flying across the room - these things really do happen.
But mostly, if you think of the personality changes shown in the Amityville Horror movies - shit like that happens, too.
Litmus test...
That's going to depend on what it is that you're dealing with. The only way I know is to bring in someone that knows what they're doing and even that's not always 100% The smarter entities do know how to hide.
Is there a reason for these questions or is it mere curiosity?
