The question becomes whether you believe that the experiences have a purely scientific explanation or if you believe it is a spiritual occurrence.

If you believe it's scientific, until more research is found on how to prevent it, against the above comment's advice, you may choose to speak with a psychologist if you wish, just as an outlet for speaking about the traumatic experiences without fear of being prescribed medications. Talking about your feelings is important, especially your fears. A psychologist may be able to get you to talk through some pattern that could cause sleep paralysis. Of course, there may be no pattern at all, and maybe it's truly random. To be honest, I haven't been able to find a pattern for my sleep paralysis.

If you believe it's spiritual, speak to a trusted religious leader. If they believe it is also spiritual, there may be some practices they'd like you to try to prevent the occurrences. Personally, I don't advocate that solely because I'm agnostic, but you need to do whatever will bring you peace. If the spiritual leader has deeper concerns than just spiritual, he may be able to point you to a good specialist.

My sleep paralysis still hasn't completely gone away. I've had it for 15 years now. But I can honestly tell you that I'm not afraid to fall asleep every night, because I don't allow my life to be ruled by fear. And you can come to that place, too. Who knows? Maybe one day, your episodes will stop completely.
