Nightmare!

A man has taken to Twitter to reveal the reason behind his disrupted sleep.

The unnamed man tweeted that he had trouble breathing once he hit the hay, so he decided to set up a camera to find out what was going on.

And what he discovered was unexpected…and slightly terrifying.

It turned out that his cat had been coming into his room and sitting on his face while he was asleep.

The man tweeted screenshots of the footage and it quickly went viral.

Most people were of the opinion that his furry friend is trying to kill him.
