Weird dream with demons. What does my dream mean?

Last night i dreamed about demons.

It started out has a nightmare that a demon was haunting me. I was in my house with family and friends. When the demon attacked (i remember a few times) he appeared outside. He was a black figure (you couldn't see his face or anything). He would use this creepy child ghost girl that had long dark color hair and pale skin. The girl would stand infront of the door (you could see through the door). She was making faces and stuff (that was creepy). She entered the house and everyone ran within the house. I ran upstairs into a room (scene ended) then i was suddenly back down stair where i was before. The girl was walking and then turned into a non-creepy girl and betrayed the demon by locking hi out of the house. (end scene) then demon and i made a deal that he wouldn't harm anyone if i came with him. So i did. Then he was nice and we got married and had a demon/human child (it there was a sex scene :C and i gave birth like 3 months later). The child was somewhat bad (very manipulative) and aggressive. She was saying she was going to hurt me for not doing something. (scene ended) Then the demon, the child(one i gave birth to in the dream) and me were at this lake. It was going ot be the end of the world and only the demons were going to survive. Lucifer was hovering in the air at night.
