Burger King says his new sandwich is "clinically proven to cause nightmares".

At the time of Halloween, the fast food chain will release Monday its "Nightmare King", which will be available until November 1 in participating establishments of the country.

This "spooky sandwich" consists of a quarter of a pound of flame-roasted beef, a crispy chicken fillet with white meat, melted American cheese, thick bacon, creamy mayonnaise and d & rsquo; Onions on an iced sesame seed bun. Yes, a green bun.

Burger King says that he has put the burger to the test and that he has collaborated with Paramount Trials and Florida Sleep & Neuro Diagnostics to conduct a study on sleep.

According to a press release, they conducted "a scientific study on 10 nights with 100 participants (or should we say victims?) Who ate the king of nightmares before going to bed".

Physicians and scientists have determined whether individuals have bright dreams by following various signals from dormant subjects, including heart rate, brain activity, and breathing.

"According to previous studies, 4% of the population would experience nightmares each night," said Dr. Jose Gabriel Medina, chief medical officer of the study, in a statement. "But, after eating the king of nightmares, data from the study indicated that the incidence of nightmares was multiplied by 3.5."

King Nightmare has a recommended price of $ 6.39, according to the company. From 22nd to 25th of October, get free delivery of Postmates with promo code "scarygood".

Scary drink?

Burger King has another scary article available for a limited time – the scary black cherry Fanta jelly.

This could lead to nightmares after drinking. Some Twitter users said that it stained their mouths.

The color of something else can also be changed, another Twitter user reported.
