I feel this song is about someone that's very lost without that special person (lover), trying to figure out what's missing and they need guidance to get them through life. When it says in the song 'let the light back into this empty room' which insinuates the loneliness and how isolated that person feels without the person they love. This person always felt so excited about he/she being around them where it states 'your stories would excite me'.Whenever we think about the good things we have had and then don't have anymore we can feel down because we wish we still had that something to look forward to which highlights in the song ' down down down', and repeats three times to emphasis how depressed and unhappy that person really feels.
