I remember that when I was around 8 or so, it happened several times in the morning while waking up, that I saw someone entering the bedroom while I was not able to speak or move. It was terrifying. It must have been imagination, since nobody appeared to have noticed anything unusual.

Is there a name for such event?

There are (creepy) reports from the middle ages of figures sitting on sleepers' chests, legs, moving towards them etc.

It's clearly a biological phenomenon of some description. I've never really looked into it, despite experiencing it often. Related my general take on it below.
