Bitches Brew by Miles Davis.

I once got really stoned and fell asleep while listening to it on a loop. I had all these insane dreams where I was walking through a pitch black jungle. I could feel all this stuff, the different textures of plants, the ground under foot, animals brushing by in the night, but I couldn’t see anything: a totally non-visual dream. It wasn’t scary, just super weird. Never experienced anything like it before or since.
