Returning to the original topic, it isn't merely a matter which way the girl is spinning.
The real question is, why do you perceive a 'girl' or 'young woman' at all -- and why do you perceive a 'space' in which 'she' 'spins' (regardless of the direction).
There is no 'girl', there is no 'space' and therefore there is no 'spinning', either direction.
Just as with below, there is no "pyramid" or "corner", there are only different shades of gray pixels. That is all there is. Everything else about it is an 'illusion' contained within the mind.
This is true of all visual phenomena -- indeed, most of what we call 'perception'. We do not see, touch, hear, smell or taste the world around us. Photons don't get into the brain any more than do soundwaves. When we 'touch' something, the molecules do not intermingle. The same is true for smell and taste -- except in instances of direct, chemical stimulation by psychoactive substances
-- all that ever enters the brain are electromagnetic impulses which alter brain chemistry. These impulses are contained within our neurocircuitry. Our phenomenal experience of the world, including ourselves in it, is derived from the perpetual energetic and molecular cascade within the entire brain system (neural networks on out).
The more significant and least pondered question has to do with the relationship of all that
and the far more mysterious and existential properties of being
. What "experiences"? I've begun to come to the conclusion that for the most part the answer to that question is "nothing". IOW, for the most part, our experience of being is no more substantive than that of a dream.
Nevertheless, all that said, there is another possibility.
