I dream a lot at night, and I quite enjoy it. I recently realised that I also dream a lot during the day.
Imagine you can cut down the present moment to an infinitely small instant. The quantum of a Nano second. Not „now“, it’s already over. „Now now“, as they say here in Africa. With a blink of your eye, a million „nows“ have already passed.
We can assume that this „Now“ really exists. Let’s take that as a working hypothesis. Otherwise everything would be a dream.
I am sure I am not the only one: While dreaming, I have no doubt that it’s real. My brain is sending me all the signals of the woman I always wanted to meet or the boss I never wanted to meet. When I wake up, sometimes I am happy that elephant-sized mosquito did not bite me; sometimes I wish I had been that smart, rich, and beautiful guy. My brain realistically produced both things during sleep.
We acknowledge easily that a night dream is a brain fiction. We talk about it openly. Can you imagine? Last night I dreamed I was flying.
But the brain does also a good job in creating daydreams. We dream about all those times, an infinite sequence of quanta of nanoseconds. These moments are not the present. They are either in what we call the “past” or the “future”.
