this morning (this was after i went to sleep again and then i woke up) after i woke up for the second time, I opened my eyes for a little bit but didint move, but then i tried to move and i couldnt. I tried my legs, then my arms and my waist but nothing was working. so then i got a little worried but then i tried my fingers and they moved and then suddenly i was able to move the rest of my body. Was this sleep paralysis or is this something completely different?
