Thank you for sharing me this! I've checked it out and I agree one of the major causes of sleep paralysis is bad mental health. My high school years is one of the most problematic times of my life. There are details I'm not ready to share yet in this blog and I suspect those were major factors of my having sleep paralysis.
Recurring sleep paralysis? There's an info about it here. I had that too. Two episodes in one night. But I had worse: one night I woke up from a sleep paralysis only to find out I was still in another dream, then another episode happened.
Anyway, wishing you the best health. Thank you again for the link.
