This song came out as I was a sophomore in college, and one of my nighttime habits on campus was listening to the radio (and calling the nighttime DJ at WKQQ to play Roy Orbison, which they all refused to do). I've listened to The Cranberries since then, and Dolores O'Riordan has only grown over the years. She and the band were only a couple of years older than I was, so it was especially hard to hear that she drowned due to alcohol intoxication.
Dreams is a haunting song about love, and one's first love in specific. Even 25+ years later, I still love hearing it pop up on the playlist.
