Laying in Bed

I lay in bed
with a thought of Ewe
in my head.
For counting of sheep
is supposed to help you sleep.
I hear a neigh in my ear,
for I can't disappear,
as the evening is nigh.
Oh, wait. I need to explain,
I'm talking of reign;
not talking about rain,
for if I do there,
it will be pain (ful)
as I place my head through
the window pane.
