Can you play video games in your head at will? For example, I dreamt of playing Halo 3 on Legendary difficulty in my sleep and woke up as soon as the Prophet of Truth got stabbed. My brain manages to recollect the physics engine and textures because I played it so much, so right now I am immediately driving on a mongoose on The Covenant with a robot co-op player and we're making our way to the Hornets. Or, I'll suddenly decide I want to play Gears of War 3 online with robot players. I can manage all the enemy players' movements and shots realistically. Before I could only determine what was happening within an area of 3 metres from myself, but now I've gained the ability to make NPCs fight each other in the background whilst I fight people nearby myself. I'd like to dream of Crysis 3 and see what my brain conjures up. It's like a lucid dream video game. And yourself?
