Recurring nightmare about what I think is a demon, very vivid, usually occurs right after I wake up. Help?

So I have had this dream over 20 times. It started over a year ago at my old house and has started again at my new house. I wake up in the mornings to tell my husband goodbye and then I must drift to sleep, but I don't remember falling asleep. The room starts shaking and I hear just loud pulse of air. I am afraid to breathe in because I am afraid of being possessed in the dream and I can never open my eyes to see what's in front of me. It is usually exactly the same but changes slightly as my possession in bed changes, if my baby is laying with me etc. I sometimes am able to yell things like you can't have me or you won't take my baby. When I wake up from this it seems like I never was asleep. I am catholic and was going to have the house blessed because I am so scared. The first time I had the dream I had to go to a friends house because I couldn't be alone. I am usually not superstitious. Please help.
