I've been having dreams about demons.?

In this dream I was waking up and when I looked up I saw this gargoyle looking demon but without the wings. I got off my bed and I started to say Jesus over and over again. The last thing I remember about it is that I saw this wisp white fog thing land on the front corner of my bed were I in real life pray on my knees. What does that mean ? I have also have seen other things like shadow people and other things as well can anyone help me? What do I do? And I don't do drugs or am crazy or thankfully els so no stupid things. Help!
