Lyric discussion by Designit4me 

Some people take the term literally ghost, like fantoms in the night. I take more on the idea he is singing about our memories. Things that happened in our past that sometimes haunt you like a ghost. Usually things if you can turn back time and undo you would. A lot of times your sitting and something someone said or just seeing something reminds you of something you wish never happened. Be it your fault or someone else’s.

@Designit4me You are definitely correct, "ghosts" isn't in the usual sense. I think the memories that haunt us can also be positive ones. That longing for another place and time that you know can never return. I visit to my hometown every 5-10 years deliberately, and there are places I won't go because the memories are sacred and I don't want to see changes to buildings, etc. It also leads to regret of "what could have been" as you compare your refreshed memories with what you know now.
