What does this dream i had last night mean?

my boyfriend and myself were skinheads marching with a bunch of them down this road we lived by when we use to lived down south and we was carrying swastika flags, as we was marching i saw black people hanging from trees and houses on fire. but everyone including us was chanting and couldn't stop as we turned a corner inside the small community i woke up what does this mean? P.S both of us are white
