These aren't really nightmares, I guess. But for a bit after dabbling with DMT, I would have entities show up. One locked me into place during what I thought was sleep paralysis. Once I realized I couldn't move at all, I saw the entity from my DMT trip. I asked it to let me out and my head flew off my pillow as if I'd been trying to wake up for a bit.
A handful of times after that, I would wake to see him staring at me. I rolled over once and he was looking at me from in my bed, too. I also began having out-of-body experiences, which I hadn't prior. I'd get this weirdly intense vibrating in my body, but usually shook out of it in fear. When I "let go" and relaxed, I'd begin floating around my room. Once in a similar experience/situation, the entity grabbed my fingers (in my dream/floaty/OOBE state) and bent them. I felt physical pain and said, "Ow! Who are you?" and heard back a demonic, "SATAN." I woke myself up right then.
They've stopped now, though. It's common from what I've read, having dreams different post-DMT. Mushroom trips are different, too, apparently. People will also dream they're being offered some DMT, take a rip, and have a full-on DMT trip in the dream. It's an insane molecule, for sure.
