Yes, the title is a contradiction but i hope it caught your attention.
While going over some scientific literature, i came across the notion, that psychedelic states come with hypersuggestibility. Could one use hypnosis while under the influence to ingrain the messages during the session even deeper into your subconscious (whatever that is) ?

I'm talking about a low dose mushrooms perhaps...

the hyper-suggestibility is one of the reasons why psychotherapy with LSD and mushrooms is possible. I believe the suggestions can guide the tripper's experience, and perhaps even be ingrained into the subconscious mind, but only to a certain degree. It must not conflict with the tripper's most fundamental beliefs. Though, most of the insights during psychedelic psychotherapy arises from within the tripper's mind, the psychiatrists may suggest certain notions to steer the trip in a certain direction.
I don't think trying to manipulate the tripper would work, since in most instances it would conflict with their most fundamental views, beliefs, and behaviors. This is why the CIA experiments conducted during the MK-Ultra (Mind Kontrol Ultra) failed, and was discontinued...
So i would *assume* that even through hypnosis while tripping, the amount of messages suggestible to the subconscious, only goes so far. But if its a positive message, our subconscious will natural be more open to those messages, and allow a deeper ingraining. Either ways, our brain is not an easy thing to just hack into; our subconscious can decide which messages to keep, and which to discard

I did a series of experiments using a Proteus mind-machin and recorded self-hypnosis tapes with mid-high doses of LSD. Overall, I did notice improvements, but twice I had freakouts when I realized that someone was trying to brainwash me and couldn't remember that it was *me*.

Would suggest using low-mid doses and having some experience with self-hypnosis first.

Edit: In Robert Anton Wilson's collection The Illuminati Papers he gives a specific method called the Thoth Ritual that uses recorded suggestions along with MJ. I haven't found it online, but will type it up to give a sense of what I had based my experiments off of.

Just pushing this to the top, to see if anyone else experimented with this.

Haha ragabr! Thats awesome, I do like the idea of self hypnosis using your own recordings.
It seems like you could do alot of work when you are being reminded of your intentions throughout your trip,
Or at least have them subliminally inserted into your subconscious while in a deep meditation.
I will definitely try this!
