Yes,that was the other option.Oh dear,this is tangled isn't it?They aren't trolling, they really think its true.
I assumed intelligence in you link as you've got some decent work going on,with the hypnosis and such.So I thought hmm ,most likely trolling.
Given that,I can understand the conviction,hypnosis can be a strong from of psychosoma and it can help with healing,in the physical as well as mental and spiritual realms.However causing growth of womb tissue,that is way beyond the scope of hypnosis,unless there are hormonal/genetic materials available to build from in the body already.
A woman recovering from cancer surgery could grow back womb tissue,as she has 'the blueprint' so to speak,in place for the body to work with.A hermaphroditic person could also do this,even if they are considered 'male' or have accepted the male gender as dominant etc.A chimeric person also,as they too have the capablility,in the 'wiring',the genetic codes and materials are stored in them somewhere within.
Hypnosis alone can give the perception but will not bring about physical change.As Ssormany put it,you are in effect deluding yourself.This dosen't have to be a bad thing,necessarily,but it should not become your defualt setting, as it is only you who carries that perception.
You can definately use this technique to help feminise your outlook and inner perceptions,just remember not to get too obsessive about it, my concern here is that you are in danger of falling too far into delusion and it may cause you anxiety/problems in the long term.
