Need your beauty sleep? Then don't go see the new horror movie Midsommar, which apparently is so scary it's keeping viewers up nights.
Midsommar involves creepy events taking place at a Swedish folk festival. As of Friday, it has an 81 percent "certified fresh" rating on Rotten Tomatoes and has gotten "generally favorable" reviews on CNET sister site Metacritic.
But it's not getting such great reviews from those who need to catch some zzzzzs. Numerous viewers have posted on social media that the disturbing movie is playing havoc with their need for sleep.
"I've never been so interested and disgusted by a film at the same time. I can't sleep," wrote one.
Now, the word is spreading. "Off to see Midsommer tonight. Didn't want to sleep anyway," wrote Luke Chandley on Twitter.
