Why do I keep dreaming about HIM!?

I noticed that I seldom have lovey-dovey type dreams, but when I do they have usually involved this ONE guy? It happned when I was younger, than when I was a teen and in that dream we were married with a kid, and now that I'm in my 20s the guy is the same, but older! he is always blonde with blue eyes. Why do I keep dreaming about this guy? I feel like we are soulmates (when I'm in my dream); I can actually feel the emotion of love and like I can never love anyone as much as him.
