Doppelganger dream about my boyfriend?

Last night i had a dream about this guy, who i ended up realizing was a doppelganger version of my boyfriend. They mirrored each other in every way from looks to family life to personality. I have read on doppelgangers and I take it that this guy I dreamed about is the "evil" version of my boyfriend. But, what eventually happened in my dream, was that we fell in love with eachother. WHAT DOES THIS MEAN?|||it means you had a weird dream
