The Light In My Head

I have a light in my head.
It turns on when I go to bed.
And in this light I can see
Everything that’s not meant to be.
I see things that didn’t go right
Except that they are magnified.
Things I said or didn’t say
Or did or didn’t do during the day
And the possible repercussions
Are all blown out of proportions.
One thing leads to another,
And all these are such a bother!
At a time when I should be sleeping,
I lie awake, brooding and thinking.
Oh! what a nervous wreck am I!
Mulling over all the ifs and whys.
Then, the morning sees me awake
With a pumpkin-like strange face.
No book, no talk, no spell, no potion
Has cured me of this condition.
I could be wrong, and I could be right,
But this adds to my deplorable plight!
And so, the night fills me with dread,
For I have a light in my head.
