Cover art for Monster lyrics by Imagine Dragons

Here is my look on this, but I think this song can be understood in a number of ways.

It tells about this guy who just wants to fit in. In some way, he's different and if he showed his true colors, people wouldn't accept him. He has taken on a role, being someone he isn't. Now, he don't like this role, not at all. He sees himself as a monster, this new him being forced onto him. He wants to escape this new role, as he sees that it isn't him.

My Interpretation

My interpretation was that the monster is like the disease or what you call his "true colors."
