I always find it funny when people assume that their drug-induced hallucinations are somehow indicative of the "supernatural," or the "afterlife," or whatever.
Don't get me wrong, I would love to take psychedelic drugs--sounds like a good time.
I once ingested half a bottle of Zoloft, and had some pretty otherworldly hallucinations.
But, why would someone assume that this constitutes evidence of the supernatural (e.g. machine elves)?
To me, the fact that drugs were required for you to have this experience implies that your consciousness is totally a result of the chemical reactions taking place in your brain.
And so, when your brain dies, doesn't it make perfect sense that your conscious mind (and everything in it, such as machine elves) would cease to exist?
