Family Slaughtered

So I've dreamed this when I was young. We had a small home, I was living with my mother and my 10 years older brother. I wanted to drink some cocoa so we left to the grocery store to get some. It was daylight when we left, and it's darkened while we got home.

As I've opened the door, my brother faded in an instant from me and the room before me was lightened. There were spikes on the floor, evenly, perfectly divided, each one hold one of my families head, severed from their body, blood dripping on the floor. I watched this for a while and woke up.
