This is keeping me from sleeping right this minute despite the fact I'm exhausted. I've had these ever since I can remember, I think mine are best described as level 4 (which is supposedly difficult to achieve without drugs or meditation, but I've done neither).
Problem is that mine are terrifying, which is why I can't sleep. I see horrible monsters running around in the black space when I close t eyes, sometimes coming towards me. When I was a kid I could also see them when I opened my eyes. They're beyond my control, I can't direct what they do.
I'm so sleepy but every time I close my eyes I get freaked out its not fair
