What does this mean?( A dream I had like 11 years ago)

I remember when i was in 3rd grade about 11 years ago i had this dream and still remember it vividly. I was walking in some dark city with my 3rd grade teacher. it was in the winter, really icy and cold out.anywayz we came upon an ice skating rink in a park, right near the street. at first nothing was there. then all of a sudden my teacher dissapeard. i was staring at the rink again and all of a sudden about 4 or 5 guys started to fade into view skating. they were tall and slim, dressed in all black, had pale white faces, and a black beanie on. they were skating around for about a minute or so and one of them saw me. he pulled out a pistol and the other guys pulled out their guns. they were coming toward me and started shooting. now i started to run away, in this bleak, dark, cold, city. There are no leaves on the trees, snow on them, and no people at all. the street lights are on so i can still see. i looked back and saw a bullet in slow motion going right toward me. then i woke up. what does this mean?

ummm...nada
