A Terrible Dream

This is a dream that I had when I was really young and I wish I could forget...

It starts of with me standing next to my dad in the backyard of a house. [I don't know why but my dad basically doesn't help me in this dream.] My mother is strapped to a white chair and there is an apple on top pf her head. There also was a man standing next to the chair and holding a gun. He looked at me and said, "darling, shoot the apple on your mother's head or else I shall shoot here." He handed me a gun, but I had no idea how to use it. [I should've just shot the brains out of that guy.] I pointed the gun towards my mum and tried to aim for the apple; I shot, and she was dead :(. My dad then grabbed me and started running really fast. (my dream has changed to birds eye view). He ran down the street, away from the scene and then it all exploded. A BIG explosion generated from my mum and destroyed everything;house and garden. My dad was running and fire was right behind us, then I woke up...

I have never been able to forget this dream. I killed my mother and then my dad and I died from the explosion.
