I have this problem, whenever I go into sleep paralysis, I wake up.
For some reason whenever I enter SP it feels like there's a sort of ''sour'' pain inside my head. I don't know how to describe it well but it's not a pleasant feeling.
I did have several succesful attempts with entering a dream after sleep paralysis but for the majority of times I just woke up during the SP.
Does anybody else experience the same as I do?
