Lyrics:

The secret side of me
I never let you see
I keep it caged, but I can't control it
So stay away from me
The beast is ugly
I feel the rage and I just can't hold it

It's scratchin' on the walls
(In the closet, in the halls)
It comes awake and I can't control it
Hidin' under the bed
In my body, in my head
Why won't somebody come and save me from this?
Make it end

I feel it deep within
It's just beneath the skin
I must confess that I feel like a monster
I hate what I've become
The nightmare's just begun
I must confess that I feel like a monster
I... I... feel like a monster
I... I... feel like a monster

My secret side I keep
Hid under lock and key
I keep it caged, but I can't control it
'Cause if I let him out
(He'll tear me up, break me down)
Why won't somebody come and save me from this
Make it end

I feel it deep within
It's just beneath the skin
I must confess that I feel like a monster
I hate what I've become
The nightmare's just begun
I must confess that I feel like a monster
I feel it deep within
It's just beneath the skin
I must confess that I feel like a monster
I... I... feel like a monster
I... I... feel like a monster

It's hidin' in the dark
Its teeth are razor sharp
There's no escape for me
It wants my soul, it wants my heart
No one can hear me scream
Maybe it's just a dream
Maybe it's inside of me
(Stop this monster)

I feel it deep within
It's just beneath the skin
I must confess that I
Feel like a monster
I hate what I've become
The nightmare's just begun
I must confess that I feel like a monster
I feel it deep within
It's just beneath the skin
I must confess that I feel like a monster
I'm gonna lose control
It's something radical
I must confess that I feel like a monster

I... I... feel like a monster
I... I... feel like a monster
I... I... feel like a monster
I... I... feel like a monster
