It happened to me a lot but fortunately I've discovered the 'trigger' that causes it for me. When I'm in bed I have to keep both arms above the duvet, if I don't there is a very high chance I will have sleep paralysis. I believe it's related to heat. If I get too warm it is triggered and keeping my arms above the duvet prevents this.

I've tested the theory quite a lot simply by trying to trigger sleep paralysis (I wanted to when I was experimenting with lucid dreaming) and simply covering my whole body (except my head) worked most of the time.
