Wow, please pardon my insensitivity before. I haven't heard of anything like what you're describing (closest thing would be sleep paralysis, which evidently isn't close at all). Could I ask how exactly you recovered? Also, have you actually tried any hallucinogens and the like to compare your experiences/dreams with?
Nah nothing is insensitive about what you said. You have heard of some what I'm describing. It's a combination of some undiagnosed (or undiagnosable, as I've been told) sleep disorder and some form of anxiety/panic related psychosis, which all can go hand in hand. Ever had a really mentally and physically exhausting day? How did your sleep go? Now imagine doing that every day for years. That particular story is just the sleep aspects of what I have experienced. Those were mild, to be honest. As for recovery, a certain portion of people with psychotic symptoms can recover through proper treatment over the course of a few years, and it can become latent. I still have symptoms occasionally, but it's manageable and not a big deal anymore.
