the sleep paralysis explanation is something else, isn't it?
amazing how the mind works.
i wouldn't worry.
if it happens again, you can talk to you md. and see if anyone else in your family has these experiences. if it's a problem, get a referral and talk to someone like pegasus said.
i understand some foods, like MSG, can trigger nightmares/vivid dreams in some people.
best to you ...
peace,
