Dali's gotta be one of the most authentically strange motherfuckers to ever walk the planet.
He never did drugs, but I'm convinced that he had some (mal)function in his brain giving him a constant drip of pure DMT.
While I jest, it's not that far from the truth... he did experiment with hypnogogic states (mental state between being awake and asleep) in order to alter his consciousness. If I recall, he set up a contraption where he would sit upright in a chair, holding a fork and he would put a ceramic plate on the floor under the fork. As soon as he'd start to doze off, he'd drop the fork which would make a loud clang, and wake him up. He'd then immediately begin sketching/painting/writing/etc. while still in that strange zone between dreaming and reality.
I'm probably butchering the details, but it was something like that. Dude was just on a different plane of existence.
Given all that, I'm almost inclined to overlook all that fascism stuff... Almost.
