[pressentiment]

I think there's something in how a good shrooms high makes you feel that 'you' are less real, and that something like nature is more cohesive and real than you are used to thinking about it.

But as someone else said, the next day you don't care anymore and you don't actually think you unlocked a new dimension. The experience of what drugs feel like doesn't seem like a valid way to get at the true nature of anything.
