> The leaves on a tree are not breathing, Actually, leaves are the primary method that trees use to breathe. > Acid, and therefore a hallucination, is altering your ability to perceive reality. It is not "unlocking" any form of reality that you cannot normally perceive. Every new type way of seeing the world unlocks a new form of reality. I would disagree with the "fully experience reality", but it can definitly provide new experiences with time, space, perception, identity and causality. Those are the very topics covered by metaphysics and this it seems entirely likely that same/many people change their metaphysical views as a result.
