Well I wouldn't describe my consciousness as being particularly contained by my body, it tends to extend out, "a lot". But in the experience I mentioned, I was knocked out of my body into an OBE, and then my body was attacked immediately after, and then the entity fled, and I was sucked back into my body by the sensation of pain. The whole thing occurred over a matter of a few seconds, very hit & run. The manner in which my body was attacked was that it stuck it's hand in the side of my torso, and medically speaking, I suddenly had my one and only kidney stone. the pain increased over the next 24 hours until it was debilitating. basically the path between my kidney and bladder was blocked, and my kidney blew up like a balloon. Which "felt" like someone punching me in the kidney continuously.
In retrospect, I 'somewhat' had it coming. It directly resulted in certain very significant advances in working with my mentor, so I consider it a boon rather than a bane. And lastly, it occurs to me that the form of damage done, though extremely painful, was not ultimately harmful long term. But it "could have been" deadly I think, if it was done a little differently.
My impression though, was that knocking me out of body was just a precursor to attacking my body in this manner. It completely ignored 'me' while I was out of my body, and acted very quickly to attack my body before I got my bearings. The idea that it knocked me out of my body in order to be able to do the sort of attack it did, seems very obvious (though I hate to jump to conclusions).
I've had one other experience which leads me to believe that the body is more vulnerable when I'm not in it. But it would take a while to type out, and maybe give people nightmares hehe
Regarding falling off a cliff. I have a somewhat similar experience. A very drastic impact which I saw coming, but could not avoid. I saw it unfold in slow motion. It was 'very' life threatening, and my impression was that I would surely die. So I would call it rather similar to falling off a cliff. I didn't pop out of body when that happened. Then again, I didn't die (although I was an eyelash away from it). I think it could be said that it knocked about a decade out of my soul-body attachment though.
That too I consider a positive experience. Oh I still have a bit of a limp. But, I could feel myriad strings of attachment to this life pulling suddenly taught... strings I had not really fully realized were there. Like a web of concerns and aspirations and relationships and duties, etc. From whether someone will close my bedroom window at home before it rains, to "who's going to feed the fish", to more significant tetherings. Roots running far and wide into the world, into my life here. Visceral fear I'd long since expunged, but 'concerns'... as a sort of distant cousin to fear, I still had, and I needed to be able to see it, feel it, and know it's shape and nature. I felt much more 'owned' by things I own (both in the materialistic sense, and in the broader sense of things I count as gains, responsibilities). A camel passing through the eye of a needle indeed.
It's interesting to me that much of the experience that I am finding myself drawing from in the discussions i've responded to on the forum here, almost all relate to my practices and spiritual progression as of about 15 years ago. I feel a little bit like I am, by relating these older experiences, painting a picture of a younger me, with not entirely the same tone and attitudes that I currently embody. Maybe early-path experiences are just more relatable (or more outwardly dramatic).
