Dear brain

This is what my brain comes up with.

Dear brain.
Please stop.
One second you're going to sleep.
The next you're not.
I'm already at a loss.
So why make me think?
We both know you're overreacting.
And I don't like to blink.
So let me sleep.
Whilst you wind down.
Shall we count some sheep?
This ends now.
So goodnight brain.
