For the first time in four years, Taylor Swift was on The Ellen DeGeneres Show. She was at Ellen's to promote her new single, "ME!" The episode concluded with the famous "Burning Questions" segment where Ellen asks some and personal questions that the guest has to answer. Taylor Swift has usually been an open book yet mysterious in her own ways; therefore, her fans are always eager to know more about her. The first question that Ellen shot at her was obviously dodged because it was about her next single. Next question, however, revealed quite a lot about her sleep and food habits. When DeGeneres asked what Swift does in the middle of the night when she can’t sleep, the Bad Blood singer revealed that she involuntarily eats at night. Taylor Swift Drops A New Music Video ME!

Taylor Swift said: "I go downstairs and rummage through the kitchen and eat whatever I can find, and it's really less like a human being and more like a raccoon in a dumpster," She further said, "The next morning we walk downstairs. We're like, 'What happened here?' I don't remember." When DeGeneres asked if the eating helps her sleep, to which Swift replied, "It’s not really voluntary." Ellen asked what we all wanted to ask, "So you sleep eat? … Sounds like you’ve got an issue," to which Swift replied "Yep."

Taylor's bizarre habit may sound too ridiculous to be true, but it could be explained with a little bit of science.

What is Nocturnal Sleep-Related Eating Disorder (NS-RED)?

You must have heard of sleepwalking, but sometimes, it's accompanied by involuntary eating. People with sleep-related eating disorders usually exhibit abnormal eating patterns during the night.

Some habits can be very bizarre. The person may even cook and eat during the night and not remember any of their activities the next morning. While only a few people suffer from it,  nocturnal sleep-related eating disorder (NS-RED) can occur during sleepwalking.

Symptoms of this sleep disorder otherwise can be visible only if the NS-RED occurs often enough. The person may experience weight gain and sometimes may be more at risk of Type 2 diabetes.
