This stuff is hard for me to wrap my head around tbh. It doesn't help that I now have that family tree song stuck in my head for some reason...

"I'm my own grandpaaaaa!!!"

>You see the map of the world that your brain makes from the input

Which totally makes sense and doesn't seem strange at all until you start thinking about it as an actual image. When I open my eyes I see the world around me, that tree over there is an actual tree that I'm staring at from a distance. But in another sense it's not the world out there at all but an image of it. So that tree over there is actually an image of a tree "right here". In fact everything we see is an image that is made "right here" next to all the other images that we make. But where exactly is that image? What is it made of, how big is it?

So many weird questions come up when thought about from that perspective.
