Dream about a Fireball/ Asteroid?

I had a weird dream last night. i was standing up in my roommate's room and i saw a couple of shooting star like things outside. a few of them started going in different directions and finally one took a sharp turn and gathered up speed towards me. as it grew closer i realised it was really tiny like the size of a cashew nut. It broke through the window and hit me in the chest. I felt a burning sensation but after that i just remember laughing and saying aw man my new shirt has hole burnt through it.
