How well do you visualize things you remember or imagine? Try to imagine this: You have climbed to the top of a hill. You scramble to the top of some rocks. Ahead of you, past some more hills with trees on them, is a mountain range rising above the hills. The sky is mostly blue with a few fluffy clouds, and a plane going by leaving a contrail.
How well did you visualize that? Could you see it in your mind’s eye? Or was it just a description without an image?
If you couldn’t visualize it, then you may have aphantasia, a condition that 2-5 percent of people may have. This can affect how well we can recall things, to how we can imagine the future, and even dream.

Humans have trouble understanding very large and very small quantities. Stuff over a million, or smaller than 1/1000th is just difficult for us to conceptualize. For example, we tend to think that a billion isn’t that much bigger than a million. But there are 1000 millions in a billion.
Likewise, our understanding of time and how long ago things happened is kind of fuzzy. Here is a great visualization of time. (there are some naughty words in there, beware if you are of timid sensibilities)
One thing that I found surprising is that Cleopatra is closer in time to us now, than she is to when the Egyptian pyramids were built.
