i generally don't remember dreams (except when on certain medication, then i get extremely realistic dreams) so none of the times it's happened to me did my dream keep playing. my eyelids wouldn't even open tho. it's rough ridin' terrifying to be awake and not be able to make a single movement except rolling your eyes around in darkness.
weirdly, the first time it happened, i had saw a thing about it on tv like a week before, so that calmed me a little.
