I have a phantom window knocker
comes early in the mornings
catches me deep in dreamtime
too deep to have the wherewithal to catch them.

I used to do it as a young teenager
we called it Ghostknocking  
but we never did it in the middle of the night.

I will have to out fox them
somehow
I think it must be an adult
they will be leaving looking like they are wearing sunglasses
when I finally catch them.
