I remember very little but it involved a guy who used a typewriter and had very surreal hallucinations. I’ve never seen it I just had it described to me. I think there might have been a talking horse in his bathroom? May have involved severe drug addiction
Naked Lunch was my first thought, but, if not that, possibly Fear and Loathing in Las Vegas?
(I haven’t seen either in many years; I don’t recall anything about a talking horse, so am not very certain about either.)
This was going to be my guess*, but I’m not familiar with Naked Lunch
Not fear and loathing in las vegas but that movie is on my list. I think it is Naked lunch tbh might have to call it solved. I am asking this based on a memory of a conversation I had years ago
