I think it is this but I am not entirely certain. Will give it a watch though.

Edit: partly saying this because I would love more recommendations lol I am like 70% certain this is it

God i hope so. I think I might have hallucinated the horse thing

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

This was going to be my guess*, but I'm not familiar with Naked Lunch

Definitely not but this feels obscure and enjoyable

I don't use ai

Wow. You’re not wrong. Put the original post in ChatGPT and it spit this out…

Based on your description — a man using a typewriter, surreal hallucinations, drug addiction, and possibly a talking creature (maybe a horse) in the bathroom — the movie you’re thinking of is almost certainly:

⸻

🎥 Naked Lunch (1991)

Director: David Cronenberg Based on: The 1959 novel Naked Lunch by William S. Burroughs

⸻

🔍 Key Details That Match Your Clues: • Typewriter: The protagonist is a writer named William Lee, a clear stand-in for Burroughs. He uses a typewriter that transforms into talking, insectoid creatures. • Surreal hallucinations: The film is drenched in bizarre, grotesque, and surreal imagery, blending fantasy, addiction, and paranoia. Hallucinations dominate the narrative. • Drug addiction: The story is a heavily allegorical and autobiographical portrayal of Burroughs’ own heroin addiction, with bizarre substances like “bug powder” and “Mugwump jism” substituting for narcotics. • Talking creatures in strange places: There’s a famous scene with a talking insect-typewriter in the bathroom. While not exactly a horse, the strange, chattering creature may have been misremembered as one — not uncommon with secondhand descriptions of this film. • Style: Directed by David Cronenberg, known for body horror and psychological surrealism, the film mixes elements of Burroughs’ novel with aspects of his real life, including the tragic incident of him accidentally killing his wife.

⸻

Why It’s Easily Misremembered or Confused: • Naked Lunch is notoriously difficult to summarize, intentionally disjointed, and dripping with psychological and hallucinogenic themes. • The nonlinear plot and talking typewriters are commonly cited as the most memorable (and baffling) parts. • Even viewers who’ve seen the film often describe it as something they can’t quite explain — which fits your description well.
