I have an active imagination so I never really needed it. Right now, while I'm sitting in the chair, I can also feel myself going through the chair and the ground and earth and down to the center of the planet, or floating up into the sky into space, or dispersing into a trillion pieces, or transforming into pure energy, or see a drawn sketch outline of myself typing at the keyboard. But, it's not a result of having tried LSD. I don't drink or even smoke pot - neither of which did much for me. I thought that way when I was 11 yrs old. Just how my brain is wired.
