I had this for years and it comes back every now and then.

At first it was absolutely terrifying as I "heard" people walking next to my bed, "felt" my mattress being lifted, "seen" things floating around and other (now) pretty cool hallucinations. Now I'm able to get fully conscious during the process and realise what's going on, but I still have a hard time when I feel I'm suffocating :(

Just an advice, the trick is to focus your brain on your breath, don't panic and raise your awareness of everything that surrounds you. It will calm you down although you won't be able to move or call for help.
