Hey, I'm 36 years old and have been getting them all my life....I to did believe-maybe still do a bit-that there are spirits involved in these crazy nightmares. the best way that i found out to deal with them is to not be afraid...i was told to pretty much confront the evil entity-if you can call it that-by cursing at it...in Catholic religion the use of bad words to evil spirits makes them leave, and sometimes forever...So when I have one of these paralyzing dreams and start to feel someone is there and cant move to see them, I begin to curse at them and tell them to leave...the dream seems to finish faster and then I wake up fine, with no fear...Hope this helped!
