NETFLIX's Unsolved Mysteries fans have been left petrified and "too scared to sleep" after a chilling episode involving UFOs in Season 3.
The creepy series returned to the streaming service this week with the first three episodes of its third season.
But the second episode – called Something In The Sky – has left viewers horrified, as it examined a series of UFO sightings over Lake Michigan on March 8, 1994.
The episode saw meteorologist Jack Bushong introduce viewers to the night in question, saying he saw large, unidentified, bright objects in the sky.
It was also revealed in the episode that there had been hundreds of similar reports of UFO sightings the same night.
One woman said she'd seen a "waterfall" in the middle of the lake leading up to one of the lights thousands of feet in the sky.
As its Unsolved Mysteries, viewers were not shown any concrete evidence, but the episode did include testimonies from experts and radar operators who saw the UFOs too.
Viewers got to see recordings of some of the reports that were made to emergency services, and this seriously freaked them out, with some struggling to go to sleep after watching.
One person said: "This season of Unsolved Mysteries is all the feels. I always skip the UFO stories, I'm glad I didn't this time around. And now I'm scared to go to sleep."
Another tweeted: "Lady from the Something In The Sky episode about the UFO sighting said she 'hopes everybody in the world can see what they saw that night'. No ma'am. I'm good. I believe y'all and that's enough."
