I have been regularly experiencing something really weird when falling asleep out of schedule or not especially tired.
I dream of myself in bed, in the exact same position I felt asleep in, and with the exact same surroundings around me. I have no control over my body. The weird part is - I can feel my legs, and my arms if they are free, lift up in the air and move around as if someone was grabbing them and repeatedly lifting and lowering, lifting and lowering. When this happens I am always prone so I am never sure whats going on.
This is really spooky and does not have the "soft" atmosphere of regular dreams; while it's happening I _know_ it is a dream but unlike lucid dreaming I have absolutely no control over it; and the fact that the surroundings are the same - and it feels like you never fell asleep - always make me doubt it might be real. (In regular dreams you usually dont care if something is real no matter how unlikely it is).
This can go on for hours of real time.


I am not _that_ troubled by this but I am really curious about whether it is a known condition, and where I could read more about it.

Thank you!
