Oh boy , you are in for a fun time :) I personally didn't try mushrooms with hypno as I cant find them, but I dropped 100-200microgram of acid solo a few times and listened to a lot of hypnosis, especially the bambi sleep series. I don't know how shrooms vs lsd will be, but from what I read around it seems to be a similar experience. I am not familiar with any of the files you have, so I cant really say, but this is my experience:
My trips focused on sissy/bimbo/Bambi content, if this your cup of tea, hypnocypher & broken666 & Bimbovision TV on pornhub have some really good videos if that is your cup of tea.
Something that I did that made the audio tracks 10times stronger for me was to use:
1) Download a folder with a bunch of hypno & sissy gifs and use it with FlipFlip https://github.com/ififfy/flipflip (Goonietor replacement after tumblr dropped porn).
2) Play some intense psytrance music like https://www.youtube.com/watch?v=mh79aSX67Rs
3) Make a playlist with the audio hypno for 2-3 hours and just get your brain melted with hypno ;) My playlist was mainly Bambi sleep stuff, and it works very well.
Just as a fair warning, the psytrance music especially can be VERY VERY intense. I dont know how much experience with psychedelics you have, but for me personally with the triggers of the hypno and the music there were times when I felt truly trapped and helpless with the hypnosis. Everything that the files were saying felt very very real. Stuff like body modification, brain drains, metling, etc. becomes your reality and you believe it's real. It's very intense and can scary to be honest, but if that is what you want, it will be a very wild and thrilling ride.
And another thing from my personal experience, those trips kinda "ruined" drugs for me…and what I mean by that any time I smoke weed, do acid, or any other drugs with friends or without the intention of listening to hypnosis, I find myself "triggered" and start slipping back into that extreme hypno headspace. It's been over a year now since I tripped and I still think of those trips.it's up to you to see if it was worth it.
And my feminization & bambi fetish turned into another level and I started dressing much more often. So be careful if you dont want to have any lasting changes. I believe tho if you have a trip sitter or a close friend or someone online to talk too about the experience afterwards will be very helpful as it will help bring you back to reality.
On a last note, have some normal trippy things planned out too in case you lose interest in hypno, and try not to cum too soon ;)
Other than that, headphones in a dark room for best results.
And good luck :) let us know how it goes.
