freaking out about nightmare

I am currently 38weeks pregnant and last night both me and my husband had the same type of nightmare. He was dreaming of our baby sitting on his lap and looking at something and when he looked up it was a demon/ ghost thing. I also dreamed about a ghost lady/ demon walking up and down our passage trying to get into our bedroom. We dont whatch any tipes of horror stories or films and its just weird that we had the same type of dream on last night. What could it mean??
