What does this weird dream mean?

[Julian L]

Well, i was riding a bike and i jumped a gap, but missed and my bike hit a girl in my class. She died, then her mom came up. punched me in the nuts, and threw me into her car. She then drove me to this cliff, threw me out again, onto a rock. She ripped of my clothes and began to rape me, moaning that i will give her another child. I was in such pain the whole time. What seemed like days later, she got up, and forced me to lick the sweat from her body. She sat on my chest, still naked, and began to pound my chest with her fists, discussing what she would do with me now. She decided to smother me with her foot, but she dragged it out. She stood on my throat for 30 seconds, and then got off. She did this many times. After she was done, she put her undergarments in my mouth and covered my nose. She laughed while choking me. But right before i passed out, she took it out and punched me in the face until i was begging her to stop. She told me to beg for death, but i didnt. So, she made me dress her, and threw me off the cliff. I heard her screaming laugh before i hit the ground. Now seriously, i have no idea where this came from. I have no clue as to how this came into my head. I was wondering what this dream means. I'm actually really confused about what it means........ thanks for the help
