Kendall Jenner just confessed she has this scary condition — is it what we think it is?

In a preview of Sunday’s episode of Keeping Up with the Kardashians, Kendall Jenner reveals that she has a health concern. In the preview, she talks about waking up in the middle of the night and being unable to move. Kris Jenner tells her it’s probably just anxiety, and it might be, but Kendall is clearly upset about what’s been happening to her, and we totally understand why. Can you imagine waking up and not being able to move at all? That sounds absolutely terrifying, and we hope the next episode also includes Kendall finding a solution to her problem. Uhhhh, Happy Halloween?

Luckily, despite the level of scary being off the charts, it sounds like what she has is not super uncommon, and also not very dangerous. While we definitely can’t be definitive (hi, we’re writing an article about Kendall Jenner, we’re not doctors) and Kendall should def seek the help of an actual qualified medical professional, it just sounds like she has is sleep paralysis.

Sleep paralysis is basically just your mind waking up before your body, which seems like what Kendall Jenner is describing. Interestingly, it’s also one of the leading theories or explanations for people seeing ghosts or other uglies: Sleep paralysis can also be accompanied by hallucinations.

Check out the video of the preview below!

The leading causes of sleep paralysis are genetics and sleep deprivation, and treatment can be some fairly typical medication or simply for the patient to get their sleep schedule under control. Given the fact that Kendall Jenner seems to have a lot on her plate, our money’s on the latter being enough to solve her problem. Catch the new episode this Sunday on E! at 9 p.m.!
