Insomnia

Some window seems to be banging against the sill,
and I cannot find it.
I'm afraid I know which window it is,
and of what I may find behind it..
The dogs have been barking, that cannot be good.
This is a very very quiet, dark neighbourhood.
I live alone; I'm afraid of being alone,
I wouldn't like living with someone.
and I'm afraid I'm not alone...
