I find
That scorpions of the mind
Run rampant in sleep.
To keep
Them at bay
I shall away
And write.

They caper
On paper.
But the thing
Is they will
Return to sting
And bite.
At night.
Therefore To still
The thing that would kill
I must write.

—

“Oh, full of scorpions is my mind, dear wife!
Thou know’st that Banquo, and his Fleance, lives”.
Macbeth: Act 3, scene 2.
