I had
sleep paralysis more as a kid, and only once that I can recall with any kind of looming figure. I can still get it occasionally, but it doesn't bother me much except for the nuisance it can be when I
want to get up.
Recognizing it (and the phenomena below) for what it is has taken the fear out of it. I either just lie there and wait for the rest of me to wake up (like
Uma wiggling her big toe in
Kill Bill Vol 1

) or fall back asleep for 15-20 minutes and wake up normally.
I also have
lucid dreams and nested dreams (dreams within dreams, like in
Inception). The nested ones can mess with you, but lucid dreams can be fun.
