ABSTRACT
Dreams are fascinating. For many thousands of years humans have been intrigued by the bizarre world which author enter through sleep, and all sorts of explanations have been and are suggested for this biorhythmic behaviour. Rose's neural theory suggested that dreams are just the result of the brain's random firing of neurones. These firings then trigger memories and the brain makes a sequence or narrative out of this mixture. A further neurobiological theory was suggested by the Nobel prizewinner Francis Crick and his colleague Graeme Mitchison. Crick and Mitchison suggested that dreaming is simply the rubbish-disposal system of the brain - the author dream what he discard, as he discard it. Learning involves the laying down of new brain connections, new circuits, and not only are some likely to become irrelevant as time goes by, but also our brains are likely to make some mistakes in forming connections.
