Fully agree. I've never done psychedelics, but years ago when overworked and by lack of sleep my mind went into a severe state of hyperassociativity. Though a serious health danger (feeling as if your brain gets cooked) it was a magnificent experience. Everything I saw with my eyes triggered an explosion of associations. I felt as if I could pierce the mysteries of the universe, perceive the future as it unfolded before me, and was sure that a higher entity existed. Until.. it became too much and I needed treatment and medication to bring me back to earth. The brain is a powerful machine.
