Why am i holding a snake...?

I'm not really sure where my dream began. So from what I remember I was walking along Ashland n what lookd like 18th.(Chicago). I was with some chick, a guy, and a snake! Normally I would freak out I don't like snakes. Anyway I end up carrin the snake the dude told me to hold him by the mouth so it won't bitr. Soon enought the little jerk bite my tongue and I was scared.the other guy took it from me and then he was touchin me for no reason. Then later as I get close to the bus station I get into an argument with another kid. Then i meet up with my nephew. This is where it gets strange we walk around the wrong side of the neighborhood and I walk him by the slums and pick up a three wheels bike with the peadles on the side. I don't know how that's was possibel. Then we ride into a gardenin class to ask where the bathroom is at. Then I wake up.but I'm nore interesting on interpreting the snake scene.
