Burger King will begin offering the "Nightmare King" next week and it will be available through Nov. 1.
The spooky sandwich is made with a quarter pound of beef, chicken filet, American cheese, bacon, mayonnaise and onion. It's served on a green sesame-seed bun.
Burger King is claiming that the special burger will literally induce nightmares. The fast-food chain claims it tested 100 people who ate the burger over 10 nights and saw a 3.5 increase in nightmares.
This isn't the first time Burger King has released a new sandwich during this time of year. In 2015, the chain introduced the Halloween Whopper and it included a black bun.
