Pennywise

I'm falling down, I'm staggering
I'm here and then I'm gone
And if you try to find me
I'm nowhere to be found
I'm in somebody's shadow
In someone else's dream
I'm in your girlfriend's mind
As funny as it seems
I'm here and then I'm gone
Sometimes I pass right through you
When you're down at memory lane
Sometimes it's only me in there
That causes you great pain
When you gonna realize
When you gonna face
All you and me went through was
A pleasant little phase
I'm gonna find you
When you least expect me to
You'll never find me
Unless I want to be
