A lack of sleep
has been linked to poor cognitive function, erratic behaviour and low creativity. Dreaming
(which typically happens in REM sleep) is a simulation of reality with full visual imagery, sounds and intense emotions yet your muscles are temporarily paralysed - allowing for rest as you enter this subconscious state. From a neuroscience perspective, sleep draws on semantic and episodic memories
- to create interesting new synapses. Episodic memories concern the individual's personal experiences, whereas semantic memories are facts and ideas abstracted from personal experience and learning. In simple terms, this means that when we dream, our brain makes connections between a whole bunch of different things to form brand new, interesting connections - laying the foundation for creativity. All while being completely unconscious and undisturbed by the noise of the outside world. How awesome is that?!
