Right away, gotta FLIP it. ;)

Short clip below talks about the brain and how it processes optical illusions. Towards the end:

"But the brain in turn is putting together, with that new information coming back, all sorts of memories from the past and also it's comparing what you're seeing in the center with what's on the outside as well."

It's interesting VK, because this made me think of another post you made this morning where you said:

"Been going thru my day and having flashbacks of dream scenes that I kinda remember. They are getting entangled with real memories."
