Why your mind is a bit like an 8-bit computer game about a 2000AD character

Very much struck by this quote from the Williams & Penman Mindfulness book on perceiving the wandering mind
 
"For the briefest of moments, all of the thoughts, feelings and memories that flow incessantly across your mind will become apparent. Many of them will seem utterly random. It's almost as if your mind is digging round in the back room, offering up possibilities to gauge if you - your conscious awareness - like them or find them interesting in some way."

Whch is odd - because it's a near-perfect description of the command interface for Sláine - a bizarre Spectrum adventure game based on 2000AD's Conan/Cúchulainn splice. 

Watch this quick demo and it'll make sense. Sort of.
