Absolutely beautiful! I've had this experience with psychedelics and also with weed edibles. I've also had this experience a couple of times sober. It's the most beautiful feeling there is. One time, a mystical experience cured me of a decade long eating disorder!! It was amazing! I was walking in nature, at night, on LSD, listening to Alan Watts' talk on The Inevitable Ecstasy, and when he gets to the part where he talks about the body as a whirlpool, I suddenly realised how true it was, that this "self" I'd tried for so long to control, without success - did not exist in the way I thought. That it was a character I'd created. That the "real me" was the whole of existence. Ego death perhaps, but it didn't feel like losing anything, except limitations and burdens. Instead I felt I GAINED everything. Or saw that I had always been everything and always would be. And then I laughed out loud in pure joy, because my eating disorder was gone, and so was my anxiety and perfectionism.
It's been over 18 months since that night and I'm completely cured of those disorders. It's not that I never have anxious moments but the pattern of thought, the "overcontrolled" way of seeing myself - it was all gone. I'm free.
Truly lifechanging.
