I had no hallucinations - they may have been inhibited by my absolute panic.

It was a very long time ago for me but from what I can recall -

I felt immediately mostly disconnected from my body, and like I was constantly falling or about to fall. I essentially laid there starfished on the bed telling myself over and over that it was supposed to be really short and wondering if I’d just killed myself until it passed, then got up and decided I’d never touch that shit again.
