Scariest Dream Ever!

I just barely woke up from a dream that scared me horribly. I'll Start right away.

So First it started I was in the passenger seat with someone driving and rumors had gone around saying that Ellen Degeneres had died saving a baby from drowning. The person beside me, the one that was driving, said "You can see her with her webs. She's walking. Look. Pretty Creepy, Huh?" In my dream I had known why she had Webs/Strings in her hands. She had a show where she showed them.

Next thing I knew I was at my grandma's house. The lights were off. They were not in the house like they should've been. I went on the porch and saw a girl trying to drown a baby. I wacked her head with what seemed like a baseball bat, And Somehow the baby came up and had a broken neck and was still recovering from that. I Lie Her (Baby) Head on my shoulder, and the woman who was drowning her jumped in the water and tried to drown herself. Somehow that didn't happen. And She went in the house to tell me off, and I locked her in the house.

Somehow I did not have the baby anymore. I went to the driveway and tried to hurry before she came out to kill me. I opened my truck door, which  seemed like Bella's truck in Twilight, But a shiny black color. I had no idea how to drive it, but I seemed to do well.

I drove up the road to my house, and all the lights in my house were off, accept the Living room light. I remember calling out, "Mom?" "Mom..?" And "Momma?" Then I start hearing what sounded like little knocks coming from my brothers' bedroom door. These sounds were REAL LIFE, they somehow must've gotten into my dream. I decide to go open the door. I went slowly. I remember me saying, "It's Just A dream. It's Okay." Then I hear the knock again. This wasn't real life knocks. The knocks were louder. The last knock was the loudest, and that seemed to wake me up.

This might not be scary to you, but it was scary to me. Does anyone know what this might mean? Every dream has to mean something. This was a scary dream to me, and Im still a little scared telling this..
