I am playing with this notion of mind that creativity is one realm where varied levels of consciousness are necessary. Sometimes we depend on that upright alertness, that mental acuity which relies on good access to working memory which is seated in the prefrontal lobe.
These are the times when all the senses are enlivened and so is our computation. Taking in all the processing data constructively and efficiently. Maybe (not literally but metaphorically), akin to wild animals returning to a well chosen partially concealed water hole. This is not one of those times collapsed periods full of the adrenalin rush of danger. Nor is this the time of ease and restful refuge. There is access to a lively comfortable mixture of resources, gleaned from ability, knowledge, experience, and a both familiar and novel situation. This seems like a reservoir for a certain quality of creative conception.
Alternatively there are those dream- like states. Distinguished from literal dream states when the senses get to retreat and we are offered a restful period of mind play. These are waking dreams that resemble sleeping dream states. Both occur in the intimate play of psychotherapy.
