What is it: A Harvard psychologist theorises that dreams are basically extra “thinking time”, but thinking that it is more visual and ‘free’, making it better suited for solving problems requiring “projected visualisation” (e.g. innovating a device) or thinking “out of the box” (e.g. approaching a problem from outside the conventional wisdom).
Why is it cool: Evolutionary principles suggest that biology tends not to be wasteful. So, for something like dreaming, which has been around for millions of years, it must have some functionality – and certainly empowering creatures with a second mode of thinking would be an advantage! Besides, it’s a cool way to explain waking up with one of those “ah ha!” moments!
