Lately it has seemed like I can predict my sleep paralysis, or as if there's a secret code in my brain that causes it. I have many memories of me waking up, and then thinking of something that gets me in sleep paralysis. I'm not sure what it is everytime, but I'm sure I've predicted sleep paralysis a few seconds before it happened. Last time, I tried to make a rule for how to think, but I was obviously in a quite sleepy stage so I thought that if I thought of the word "bass" when I woke up, I'd get in sleep paralysis. I doubt that's the case though
Some people say it's impossible to predict or cause it consciously. But for example one day when I woke up some time in the morning, I immediately thought of my back, then SHOOM and I had sleep paralysis. And it really feels like that's what caused it.
