May I have this dance?

I saw you sitting there
Starring off into space
So as not to startle you
I approached slowly

Mesmerized by your image
I stood in complete silence
I'm sure you could've heard
My heart beating a million miles a minute
Yet move you did not

I whispered softly
As soon as the words were out
I knew you hadn't heard
So divided in mind, I turned

The floor swirled into one big pattern
Trying to get to the other side of the room
Without crying
I heard something

Caught in a dreamworld,
I must be
For how could you
Have ever heard me?
