Sleepless nights

Oh, my days were lazy all-around
and my nights were easy and sound,
Until my thoughts set out on a quest
to explain the rationale of life at best.

You wanna ask and of course you may
What went so wrong during the day?
What would give one a sleepless night?
A crash or was there a terrible fight.

Did your friend betray you or wife?
Or you simply had gotten tired of life!
For me, it’s but personal and intricate
Death’s at the door and quite intimate.
