That is an even lower chance than I thought it would be, that just makes the whole thing weirder.
I'm the same with horror movies/scary stories- I'll listen to true crime for a day while working and feel eyes on the back of my head all night.
Sleep paralysis is a valid experience, I find it very strange that it tends to be similar for different people. I've had several sleep paralysis episodes, memorable few include one where I was being spooned by a scaly creature and another where my eyes were closed but someone was revving a chainsaw in my ear. The spooning one was nice though tbh. Also had the ol shadow person in the corner of the room one like you. I totally get how the people of olde used to think it was alien abduction.
