The “Nightmare King” features a green bun, a quarter-pound of beef, a crispy chicken fillet, melted American cheese, thick-cut bacon, mayonnaise and onions on a glazed green sesame seed bun.
In a new online advertisement for the sandwich (below), the fast food brand claims to have partnered with Paramount Trials and Florida Sleep & Neuro Diagnostic Services, Inc. to conduct a scientific study over ten nights with 100 participants. After eating the new burger, they allege, the incidence of nightmares increased by 3.5 times, according to the results.
In the clip, people are asked to eat the burger before going to bed and then they’re hooked up to a sleep monitoring machine for the night.
“I remember hearing voices and people walking around talking,” one test subject says. “When I would wake up I think I didn’t hear the voices.”

Another person says: “Someone in my dream turned into the burger. The burger then transformed into the figure of a snake.”
