There’s the scene from the movie train spotting where he’s kicking heroin and he nails his room shut and locks himself inside.
He goes through a checklist of everything needed to kick dope. Valium, ice cream, mashed potatoes, bunch of other shit, then a HUGE stack of porn magazines.
The stimulant dissociatives used to get me pretty horny when I did them. Mxe and pcp. With porn it felt like I went inside the movie and it was real and that the actors were really communicating directly with me.
A very common hallucination was that my dick would just rip off my body and I’d be holding my cut off dick in my hands and sometimes it would disintegrate like squeezing mashed potatoes or something. It was a pretty unsettling halluceination. One time I thought it was really happening but my dick was like shrunken and separated from me in some other dimension and I spent all this time traveling around these hallucinated rooms and dimensions looking for my little weird looking dick that wasn’t my real dick. It was whistling also
Then real sex on pcp - I was very horny but paying more attention to the trip than the sex.
