Question

A man eats dinner, goes up to his bedroom,
turns off the lights, and goes to sleep.
In the morning, he wakes up and looks outside.
Horrified at what he sees,
he hurls himself out his window to his death.
Why ?

Answer 1

The man was a lighthouse operator.
He wasn't supposed to turn off his lights.
When he wakes up in the morning,
he sees a giant ship that has crashed into the land, causing much catastrophe.
Unable to go on, he decides to take his own life.

Answer 2

Perhaps he was a watchman at a lighthouse, and lived there?

The light he turned out was the vital one that alerted ships and stopped them from coming too close to shore.

In the morning, after he realized his mistake, he saw that a ship had been ruined on the rocks.

Answer 3

Fire trucks putting water on his house.
