Here’s another reason to not sleep on the subway.

Video captured aboard a 7 train in Manhattan shows a rat crawl up an apparently clueless, sleeping man. When the rodent makes his way to the man’s neck, he wakes up and shrieks in horror, the video shows.

Rider Antony Lin, 31, shot the video in the last car of the 7 train as it pulled out of the 34th Street - Hudson Yards station about 3 a.m. Sunday, he told NBC 4 New York.

“I had my phone ready to film the rat since it was huge and the fact that it ended up inside the subway,” Lin said, adding that a couple on the train moved to another car when they saw the rodent. “So I see the rat crawl onto the guy and zoomed in.”

Lin said the man was asleep long before the rat crawled onto him and does not believe he could have planned it as practical joke.

“It's just insane and disgusting overall to see that. I've seen it on the tracks and platform, but never inside the train,” he said.

In recent weeks, NYPD Commissioner Bill Bratton has stressed that sleeping on subway trains puts straphangers at risk of robbery and other crimes.

For Lin, the possibility of a rat crawling up your leg on the train is more than enough reason to stay awake.

“Yeah, that certainly makes me hesitant about sleeping in the subway again,” he told NBC 4 New York.
