Invisible friend

Of all the friends I've had
None have ever been this bad
But it's not like they know

Cause it's difficult to stare
At something that's not there
Yet I do it all the time

Sometimes it's very clear
He's a product of my fear
So I just have to laugh

I am talking to myself
I talking to myself?
Oh I don't even care

How do you know
That I don't know

And how does it feel
To not be real

One minute you'll be
Next to me

And then you're gone
