Fast

There I am, on the bus. For some reason I am holding on to a strap on the outside. I'm happy and laughing. It's an adventure. It starts off slow and I know it won't last long till we get to the place so I can handle it. But it starts getting faster and faster. Weaving through the traffic and heading into the highway with cars comming from both directions. I am getting scared, gripping the strap so tight my hands hurt. I don't know when it will stop. I don't want to die but to save myself I have to let go.

Then I wake up. What do you think it means?
