Most of my dreams are totally real (and then I wake up and wonder who the hell all my dream-friends were as if I've seen them before it would have been as part of a crowd and thus not registered). The ones that aren't I'm aware I can just escape hatch if I get bored/things get too much/annoying or get back into if I wake up at an interesting point and want to see what happens.

So you reckon we're living in a simulation? :)
