I’ve had sleep paralysis 3 times in 30 years . The first time was in the 80s. I “ woke” up , couldn’t move but found myself in another room . I felt a evil presence. To my right I could make out a black shadow like figure with a hat . Then woke up. Years later it happened again but I really don’t remember seeing the hat man again . Then about a year ago I found myself woke up but couldn’t move again. This time I felt myself being slid off my bed by my sheet . I knew something evil was waiting at the end of the bed but again woke up ! My daughter has also had sleep paralysis.
