I think lyric-wise this song is something that a lot of people can relate to. It's about the fact that [everybody], you know, everybody gets this point in life... And that is what the song is about, that you're trying to hold on to the things that are important, that you try to find something that you can believe in and which is worth living, if it's family or the love of your life or (laugh) things that make your life worth [living]. And this person in the song is really disappointed [with a lot of things], because a lot of people are fake or things don't turn out the way she had hoped they would do. And this is what the song is about and I think it's something that a lot of people can relate to.

The video for this single was shot on 30 September in Berlin. It was released online on 19 October 2007. The video consists of a dream world in the mind of Sharon's character. The band is shown tied to walls of their cells, along with various surrealistic scenes. In the end of the video Sharon is shown in a hospital bed with images from the dream sequence flickering on a screen connected to her mind via wires.

In an interview, den Adel discussed some elements of the video:

The story is very short and very simple actually. It's a dream. A lot of times she sees a lot of schizophrenic things, you know, happening in her mind...

Lea: It's you in a hospital-bed there...

Sharon: Yeah, and they are monitoring my dreams, so they are analysing what I'm dreaming. And that's basically the video and it just suited best with the lyrics, because it's very difficult to express things which are very symbolic, which you can't really show in images like "hope". How do you express "hope", you know? Or "believe in something" or "keeping something real" or "people who are fake". You can image that very well in a way of a dream. That's why we did it in that way.

The video contains many elements and imagery from the 2000 movie The Cell.
