One night,a man had a NIGHTMARE.
it was the most FRIGHTENING thing he had ever experienced.

In the dream,he found himself himself walking in a DESERT.
Somehow,he had no idea how he had gotten there,but he knew he was LOST and ALONE.

When he looked down,he realized he was carrying a MACHETE in his hand.
The long cold steel blade looked razor-sharp.

The sun was beating down and the heat was INTENSE.
The man was sweating PROFUSELY,but he kept walking,even though he had no idea where he was going.

After some time,he saw a dark figure crouching down in the distance.As he approached,he saw that it was a person lying on the sand.He had being feeling EXTREMELY LONELY,so he was grateful to see another human being.

He quickly ran up to the man and bent over to help him up.
However,when he turned the man over,he took one look at his face and recoiled in HORROR.

He was looking at himself❗
In that instance,he was so overcome with fear that he raised the MACHETE above his head and without thinking HACKED the man to death.

Horrified by what he had just done,he dropped the weapon and started running through the desert.......

Trying to get away as far away from the place as possible.
With every step,his feet SANK further into the sand,but he kept on going,driven by TERROR and PANIC.

Eventually,he STUMBLED and fell to the ground.
Lying in the sand,he realized that he had sprained his ankle.....

What is going on here.
