What that means

I don't know if I should tell you
That you've been in my dreams
I can't control how you come and go
And I know what that means.

I don't know if I should kiss you
That might cause a scene
But I can hardly resist your smile
And I know what that means.

Right when I didn't expect it
You caught me off guard
My heart was unprotected
Now I'm falling hard.

I don't know if I should hold you
You know what that brings
I guess it's time that I told you girl
And I know what that means.
