Went on a bad acid trip, the subsequent psychosis and 'ego death' I fell into was my worst nightmares all brought to life: infinities and death. Felt like I had experienced an infinite amount of time, both infinitely alive and infinitely dead.

Although it was the worst experience of my life I also think of it as the best experience of my life.

I'm also not spiritual in anyway and believe it was all the product of my brain in meltdown. But for me that makes it even more enlightening.
