It is a library, an archive, a virtual art gallery. The repository of everything that you have seen, heard, tasted, smelt, spoken or thought. The ability to recall anything from any of those categories is remarkable. Why some odd name or comment pops up unrequested in contrast to the sometimes wait to recall the name of a flower is confusing. I can go though names of teachers, boyfriends, presents, films, from the 50s and 60s as well as last week. Its all stored away. Events from the 40s even, yet why are some things so clear you can almost see them, Dad shooting at a cobra on the lawn about 1954 but not what happened the next day or the day before. Eating grated carrot with orange juice which was a NEW thing to do in the 50s but what else was on the table. A comment made by someone on holiday, someone I may even not know the name of, "he worked for Hamptons", who on earth said that and about whom? Yet I remember clearly where I was when I heard it. So how does the brain select, are we in a state of hyper awareness when we hear one sentence but not the next? What is going on? I won't even mention dreams which are another feature of the brain remembering, remixing, muddling all sorts of people and places and things. I have driven around upteen towns and cities in dreams until I'm not sure which were real and which concocted by my brain while asleep. People are often an amalgamation of two or more. I have very vivid dreams which I can report and remember often for days or weeks or some even longer, often playing out like a film. I also have what I think are called lucid dreams, when you are not even asleep but just shut your eyes during the day. I can literally do that, close my eyes anywhere, waiting room, airport, kitchen table, and a dream happens. They are never about prophesising, like predicting a win on the races, but random stuff from the conglomeration of cells called my brain.
