It was induced by the same trip on LSD that induced mine, however I had a 2 hour long panic attack, whereas she played with the concept of ego death, but the same as me, didn't go through with it. Hers was less severe because she didn't freak out and just went with it, but as I stated, didn't finalize it. Again "my" theory is confirmed that this is about psychological trauma. 300+ ug LSD caused, 90+ ug resolved it. Her trip was going great until she started looping like crazy. I realized what was going on and that the only way out is 'letting go'. I pumped her full of xanax and told her to lie down and not fight it. Of course she/her ego fought it with numerous questions about reality, identity, the whole shebang of fears that comes with ego death. I drilled her into accepting and letting go. She meditated for 30+ mins and then finally went to sleep. 2 days going strong now: no visuals at all, no dissociation, etc... Of course she's changed, but in a good way. She later told me that the old trip that caused all this came back during this trip.
It makes me sad to listen to all Your theories how You've damaged your brains, etc... When the fact is that if you were a normal person before, your brain should reach homeostasis after quitting drugs in 6-12 months tops. Whatever happened to You guys during Your trip, I think you're lying to yourself about the psychological impact it has had, basically sticking to Your old ego which is stuck in the ego-dissolving or ego-death experience trip that messed You up.
To sum this up, I basically agree with the theory from that guy on YT. I'll be going the same way, but with mushrooms when I gather the balls and advance in my meditational practice. Hopefully that report will be my last visit to this website.
