First of all, I in no way advocate illegal behavior. I only share these experiences to make a point about altered-mental states.
If this post is against the rules, I will promptly delete it, and I apologize.
But I do believe altered states of consciousness (potentially including hypnotic states) can help tear down some mental walls, if only temporary. I have personally experienced at different times "losing my gender," forgetting that I am not male-bodied, framing my female body in a male way, and accepting my body the way it is. All of these instances were temporary, and had no lasting therapeutic effect other than a pleasant memory of what it felt like. I experienced this at different times with chemical aids, most of which I will not name to avoid legal trouble or allowing some one to replicate my experiences which may or may not be legal in their jurisdiction. I also, however, experienced this from smoking then-legal damiana/JHW-018 (no longer produced and recently scheduled in the US), prescribed Seroquil (I had a strange, unintended reaction), prescribed temazepam (hypnotic, anti-anxiety tranquilizer) and from non-drug induced dissociative as well as meditative states.
While I think drug-induced altered states have the most biochemical potential for radically shifting cognitive processes and removing emotional/mental barriers, in my experience non-drug induced states have had the most lasting impact on my gender dysphoria. I suggest meditating to trance beats, breathing cycles, different forms of meditation, fasting, and for at least exploring hypnosis (something which I haven't experienced). And now I've outed myself as a bit of a psychonaut and an anarchist in the same week on Susan's...lol. I hope it isn't time to find a new community.
