Cuts on the face can happen during sleep, as it is an easy to reach spot on the body (depending on how deep of a cut we are talking about). I probably would not worry that aspect too much. Sleep paralysis could happen with some parasites, but it also depends on the individual’s response to them. It sounds like a parasite in my eyes. This first thread is a list of a number of techniques that you can use to get rid of them. I personally break down and “devour” them, which I’ll show in the second thread but there are less extreme options. Pablo Santo and sage are good for them as well.
