Entertainment TV Kendall Jenner Reveals She Suffers from Sleep Paralysis: 'It's Genuinely Frightening' Jenner says she's "scared to fall asleep" because it keeps happening to her By Aurelie Corinthios Published on November 2, 2016 02:09 PM Share Tweet Pin Email Kendall Jenner‘s mysterious health scare has been confirmed: she suffers from sleep paralysis. In a sneak peek at Sunday’s episode of Keeping Up with the Kardashians, Kendall, 20, opens up about her recent experiences with the sleep disorder, in which one experiences a temporary inability to move or speak while falling asleep or upon waking. In the clip, Kendall is going over her upcoming schedule with momager Kris Jenner, who reminds her that she has back-to-back trips scheduled to Paris, Milan and London. “I don’t know if I’m going to be able to do that,” says Kendall. “Well, you’re already booked to do that, honey,” replies Kris, 60. “I can’t travel that much,” Kendall says. “I’m like, scared. I’m freaking out because of these f—ing paralysis things. I’m scared to fall asleep because it keeps happening to me. It almost feels like my heart stops.” Kris reminds her daughter that the nature of her career as a supermodel involves flying around the world, and that backing out would mean letting down designers that have already booked her and are counting on her to show up. “Kendall basically lives on an airplane,” says Kris. “So the anxiety on an airplane and the sleep paralysis is a huge problem. Sometimes it’s been so bad that she’s been paralyzed from even getting on an airplane. I’ve had to get on a plane and fly from L.A. to London just to get her from London to New York! So it’s becoming a real problem.” RELATED VIDEO: Kendall and Kylie Jenner Rescued by NYFD After Getting Stuck in Elevator: ‘Worst Nightmare!’ But Kendall puts her foot down. “I think that my health is a bigger deal,” she tells her mother. “It’s genuinely frightening and I don’t know how much of it I can do.” Keeping Up with the Kardashians airs Sundays (9 p.m. ET) on E!
