It's not unusual to dream about things from the past(ie your dad/buddy). I typically dream about my childhood home, my childhood sweetheart, and my ex from 5 years ago. Very rarely do my dreams involve my current home/fiance or my job. The weirdest dream i ever had was when I was going through a bout of depression .... I saw myself in a coffin in a funeral home.... scared the hell out of me. You can go to different websites and different interpretations. I wouldn't put too much thought into it.
