Netflix users warn new series is so 'terrifying' watching it after dark left them 'unable to sleep for days'

Viewers have issued an urgent warning to those who are considering watching a new docuseries that’ll have you unable to function properly after seeing it.

Viewers of the Netflix show have been warning people about watching a terrifying supernatural thriller that might leave them unable to sleep without the lights on.

The series, which dropped on October 7, focuses on the tales of the occult, but with a twist.

While it might seem like your usual paranormal documented case, it’s got horrors upon horrors and jump scares that could challenge any horror classic.

But the worst part? It's based on interviews with real-life people, who say the crazy supernatural encounters depicted really happened to them.

I ‘haven’t slept properly since episode two', someone said online.

Another wrote: “There is no way I’m turning off the lights and watching this at night.”

For many, this is a daylight-hours-only series.

However, critics love True Haunting.

Heaven of Horror's Karina Adelgaard wrote: “It does have quite a few of James Wan’s signature moves. Either he was fairly hands-on or the directors were inspired.

"This is far from the first Netflix docudrama in the paranormal horror niche, but it just might be the best so far.”

Decider's Joe Keller shared: “True Haunting does a good job of mixing the scripted reenactments and real-life interviews about these paranormal encounters, which is something that’s rare in the horror docuseries genre.”

The five-episode series was created by Wan, the man behind The Conjuring and Insidious.

It's scaring viewers all over, and they’re adamant you’re watching it in the day so that your sleep won’t be disturbed for the foreseeable.

The first couple of episodes follow college student Chris DiCesare as he’s tortured by a spirit in his New York dorm room in the 1980s.

Then the Miller family take the lead.

The family are renovating a Victorian home in Salt Lake City when their house becomes haunted by a malevolent force.

That’s when famed paranormal investigators Ed and Lorraine Warren, come to investigate.

While viewers and most critics rave about it, not everyone is a fan.

One person said online that it fell flat, writing: “The concise elevator pitch of Netflix’s True Haunting seems to have been, simply, another in a long list of enduringly popular but typically terrible ‘true stories’ about real-life hauntings, but with a glossy, cinematic sheen over those re-enactments.”

Another said: “What is infuriating about shows like this is that they encourage viewers to believe that paranormal phenomena might be real, without putting in any of the hard work necessary to justify that conclusion.”

If you want to check it out yourself (and feel brave enough), True Haunting is streaming on Netflix now.
