I've escaped dad duty long enough to actually read your introduction! It's good to have you.
My experiences started in horrible ways when I was younger, and I had a very...Jung-esk episode of vivid, focused, and occult dreams around 18. At that time I started reading various research on parasomnia as well as "zen mind: beginners mind." Dropped my Christian-esk wiccan practice for two years of heavy eastern study and practice.
It was after that that I began to experiment with psychedelics at 22, first with mushrooms. At 25 I broke through on DMT and returned to a more serious study of ceremonial magic and alchemy, then satanism. I've studied a lot of different works now, and what I've figured is that there are no lines. You can be full LHP and only study eastern mysticism, as long as you don't hold moral convictions about identifying as such. The left hand path is freedom, RHP is following strict guidelines to keep what works working. The big difference is that most folks identifying as LHP study both schools without losing about sleep over being evil.
I had tried acid at like.....14? I had a horrible time. Returning to it at 26 was incredible. Dion Fortune defined magic as, "The science and art of causing changes in consciousness to occur in conformity with Will," and I can tell you, nowadays psychedelics make me become magic. Taking this time to categorize and control your thinking pays big, unbelievable, and exhilarating merits if you return to the psychedelics much later. I read a couple of shamanistic books while researching the lesser work that helped a lot too. If I was to isolate what helped it was meditation, plant alchemy, and a little odinism found in setianism. The confidence and understanding, the mindfulness, it eliminates fear. Dmt was like a complete OBE, I felt myself accept death and my soul like squeezed through my nose. It felt like being crushed to the size of a point. I'm not sure if I'd call the sensations on acid that after studying for a few years vs before, it was like a ritual trance state that lasted 13 hours. Clear, in control, perceptive, intuitive, imaginative, and full of wonder. I'm glad I gave it another go.
Sorry if I rambled, I just find it so interesting that we're on similar paths but in a mixed up order! It really was good to meet you!
