If you are familiar with nature channels that show wildlife in their natural habitat, then you must have come across documentaries showing monkeys in their own natural habitat. If you are not, allow me to paint a mental image of what they look like.
Picture a lot of monkeys hanging from branches on numerous trees. All of them chattering the way only monkeys can, all at once with each of them trying to out chatter the other, and at the same time swinging from branch to branch.
A bystander might find it hard to follow just one monkey as it swings from branch to branch, and in the end, they’d just switch to watching another one, and then another one.
Welcome to the human mind.
