Derren Browns Zombie Hypnotism

Lots of people have heard of Mr Derren Brown, but I've noticed that not so many people know about when he hypnotized a normal guy within a bar, to believe he was within a zombie game.

What happens, is he programs the game to have a certain sequence of flashes within it, that will make certain people susceptible to a certain reaction, that he can then control through hypnotism. He then places a player of the game into deep sleep, whilst he transports the player into a real life scene that looks the same as the game. The player wakes up surrounded by a horde of actors acting like zombies, and a toy gun in his hand.

You Tube video of this is below, have a watch, since it is truly special.
