I had a nightmare the child I'm carrying is a demon?

I've been under quite a bit of stress, but I'm also one of those who are sensitive to things others don't notice. Not saying psychic or clairvoyant because that would be a lie. Just extremely sensitive to my surroundings and pick up on stuff that's happened in a place. I've believed for a while now that where I'm living a spirit of some sort "visits" but does no harm. Sounds nutso, I know. There are knocks in the kitchen and my fiance and I have both caught glimpses of something dark moving in the bedroom (we both know it sounds crazy but can't deny what the two of us have seen at different times, sometimes the same time). Back to my question, I had a dream that my little girl was born. Only she wasn't normal, something was bad about her. Of course, being the loving mother (I have two others, mental or physical deformities would never matter to me, I love them too much to be so superficial). Only this child, she seemed to seriously be evil. She could move stuff without touching it and she kept trying to harm her father and I. I'm excited about her coming arrival and kept looking for a subconscious reason for why I would possibly think that of my own child. When I woke up, I turned to her father and told him what I dreamt, and the moment the words "the child was a demon" were out of my mouth, there were a couple of loud knocks from the kitchen. What can this dream mean? I know it means nothing in reality, but I would like an interpretation.
