Night noises

I'm not sure if it's an age thing,  but I sometimes find myself waking in the middle of the night, unable to doze off again immediately.  This happened recently while I was staying at my sister's and the night noises were different to how they are at home. 

Hark, hark, the dogs do bark,

The cats are caterwauling,

The night is still, the streets are dark,

But sleep won't yet come calling.

What can it be that roused them so?

Intruders? Ghosts? Kids walking past?

Why can't they simply let it go?

Let me drowse off again, at last.

The frustrating clock gives a single chime - 

No good to man nor beast!

Now I won't know the actual time

For a good half hour, at least.  

I've fretted my sheets into a shroud,

It's tight, grimly constricting, 

This nighttime chorus is far too loud,

My thoughts too disconcerting. 

I toss and turn, I fret and sigh,

Watch the curtains growing light, 

Then bam! It's somehow already nine,

I must have slept alright!
