Blue, blue windows behind the stars.

I was leaving a club that was located in some kind of industrial area with a classmate of mine, it was also in the middle of the night. Suddenly, a person who was very hard to identify showed up behind us and started following us. My friend kept telling me to ignore the person and just keep on walking.
The person came closer and closer to us as we walked and when he was maybe, 10 m behind us or so, he started to run toward us(still from behind). We just kept on walking as he ran, and then, with a bang he rammed into my friend with some kind of hockey-tackle.
Just as the person made contact with my friend the dream ended.

The end.
