Woah, that was AWESOME.
Does anybody have any kind of background in psychology or neurology, who might be able to explain how someone can slip into a coma like that? I'm guessing it's probably similar to hypnosis, since about the same amount of people are susceptible to being hypnotized as well. I know it's also tied to epilepsy, right? Similar functions in the brain, anyway, since flashing lights can also induce seizures. It's crazy to think about what goes on in the human mind.
But anyway...yeah, zombies kick a$$!!
