The girl in purple

At first I didn't see the girl

I heard her laugh all clear and fair

Beyond my eyes a purple twirl

Fades away above a stair

I followed quick, no time to loose

Now in the top but she's not there

Again the laugh, was it a ruse?

I heard it down, below, somewhere

These stairs behave just like a maze

She runs and giggles always near

I search but cannot find a trace

Missing her, now that's my fear

I see her now seh flashed a smile

Behind a door to dissapear

I follow back, my eyes go wild

I am alone, there's no one here
