Weird dream I had about a month ago

Hello everyone. I'm new to the site, so I apologize if I break any rules, but I feel like I need to tell someone about my dreams and possibly get an interpretation. The dream is pretty dang weird, so this is a warning.

My dream begins with me driving a a pickup truck with a girl my age (21) in the passenger seat. I'm driving on a road near my hometown (in the middle of nowhere, basically) and it's night outside. I stop the truck and we both get out. I take a container of gasoline and set her on fire, and I just stand there and watch her run around the middle of the road on fire until she runs out into a snow-filled ditch. It's the middle of the night so there isn't anyone around. I do not know this girl.

Then, a voice inside of me says something along the lines of "time to split" and I drive away. The voice is not my own. It sounds much deeper.

I drive across a beautiful sandy beach under a bright blue sky. Everything is distorted. I'm driving really fast and it feels like I'm sailing through a vortex of sand and water spiraling all around me.

Suddenly, I'm in another girl's basement and we're playing video games. I don't know this girl, but she is wearing jeans and has light hair. I lay my head on her jeans and I feel my entire body just sink into her thighs.

Suddenly, I'm about 8 inches tall. I'm standing next to her body and at this point she's lying down on her back. Her breast falls to one side on top of me and I'm just sort of swimming in it. There's another person on her other side doing the same thing. I do not know him either. Then, the breast that's on top of me turns into a spherical metal cage and rolls off of her chest. It doesn't fall on me or anything. It just rolls.

I wake up.

After the dream I felt scared. I was affected by it for the entire day and I still think about it. Anyone have any ideas about what it could have meant?

The only person who can truly interpret your dream is you. What kind of feelings does it bring up if you go back there? When you think of the dream, what are you reminded of? When do similar feelings come up in waking life? You can either view the dream as some part of yourself trying to communicate with you, or you can view it as an interesting meaningless dream. Ultimately, the meaning (or lack thereof) is up to you. When having to choose an interpretation for my dreams, my favorite question is, which interpretation empowers me the most?
