Boogie Man, Alien, Demon or Sleep Paralysis Has anyone had this while sleeping?

Okay here's my story- when i was about 5 I will never forget this dream that sent me to my parents room I was on the moon laying down and this skinny greyish frigid thing with a tail and pointy ears was trying to force my mouth open okay the 2nd time was when i was in my early 20's i was sleep and all of a sudden something was caressing my chest by my neck bone and when i open my eyes it was a grey clayish thing with no eyes i knew it was evil so i started sayintg the 23rd psalm. and then again it was a tan being with the same dk eyes with no white. has anyone seen anything like this before?
