I saw my self in a dream in a different way what does it mean?

My dream starts I was walking in the bronx in new york city and I was crossing the street n I saw couple cops with their guns in their hands waiting I just kept walking I saw this guy walking by towards the cops and he had red scarf covering is mouth and nose with black hoody. He saw me starring at him and his eyes got big told me to stop looking at him all of sudden I dont know what it was a flash back or a memory but I saw him in desert type environment a his group of guys gun fight against this other group, his group got shot dead except him but he got shot couple of time and he kept fight back he knew how long it took so generate can explode after throwing, same with the hand guns and machine guns he knew the time of it, so he kill all of them (the action was real not like the movie ) then he saw like a halluosion of his daughter she was 6 year old blonde hair girl after that in the present time in new york city my jaw dropped and he took off his hoody and was me he started to run where the cops were at , he pull out his dual pistol start to shot at them

Thats was my dream but I dont know bout guns like that with counts and everytime and my daughter is not blonde not even 6years old so I m wondering and how can a dream have memory or or flash back when he was fighting against that group ???what does this mean
