I find it curious to consider the nature of three-dimensional space as an experience of physical interaction more than some physical reality in and of itself. Spacial dimensions do not exist in the experience of thought, after all. If one thinks of a chicken, then thinks of a brick wall, one does not have to travel any sort of distance through other thoughts to get from one to the other. The change in the experience of the two thoughts is instantaneous. (We may even combine them to form the thought of a chicken in front of a brick wall.)
What concerns me, however, is: where is the chicken when I’m not thinking about it? From what do I create the thought of a chicken?
One may say: “Well, it’s in your memory.” But then from what do I create the mental instructions to fetch the memory?
I’m not asking why I desire to form the thought of a chicken, whether it’s because I saw the word “chicken” or because I was asked to think of an animal that goes “cluck-cluck” or because I’m hungry. It doesn’t matter why I’m persuaded to form the thought. I’m wondering how I have the ability to conjure the appropriate thought in the first place.
It’s a puzzling mystery to me.
