My advice is only my advice

you give him 5grams of psilocybin mushrooms or a bit less, like 2 for starters and gradually go up because we want to "cure" him or more like make his minds existence more shinier then true

when I did LSD I was a bit like a bat in a bright cave

like, on lsd(I candyflipped) the visions are very easy to watch and get but usually they might be about aliens/technology

and on shrooms at least on 5grams of psilocybin mushrooms the feeling you get it like this "tribe" feeling that you are in unity with each other

and if you are both young he might get that "clan" mentality due to the strong trip because psilocybin is a bit different working thing than LSD and if somebody asked me which one to use on a "patient x" like yours I would say psilocybin

I say psilocybin because you get this stronger warrior like mentality from it than you do from LSD

LSD is like god on opium above clouds looking down no matter if I trip a bit

Shrooms is like the voice of the jungle, unity consciousness we all have the same power

I hope you understand what I wrote I am not a fanatic or anything like, these things demand respect and I just spoke to you my emotions

he will need a shaman or a guide who knows these things, he will need to feel safe, this is why forest is awesome, although, I got the " RISE " in my flat and gradually was able to go outside even though the effects were heavy (4 eyed people you know)

and one thing very important, the most important thing is the " meat locket" in the meat locker you see eyes and mouths and all sorts of grinning evil things

when this happens sing/breath and dance, have water, speak to the trip "can you dial this down a bit cause this is pretty rough"

I also think its would be better to have magic shrooms first than LSD because you understand the nature of LSD better when you have had a shroom trip, but going LSD first is like, lighting up the lightbulb before fire was invented
