Can anybody help me with this song i'm trying to remember the name of?

I heard the song on the radio in 2004-2006. It was an alternative song that sounded a little similar to MCR or Breaking Benjamin. The music video for the song had a man sitting in a room, and every time he looked out through the peephole in the door, he would see different bizarre, monstrous things. I know this is very vague, but for the life of me i can't remember the name of the song or even the lyrics. All i can remember is the music video. Any help would be appreciated.
