Question: what part of your brain makes your dreams?

Hey lol/123,

It’s actually never clear where in our brain makes a dream. Dreams occur because of somewhere that covers nearly all of our brains- our ‘cerebrum’. There are little clusters of neurons near a part of our brain called our brain stem that control when we sleep. When we sleep we sort out all of the information that we’ve gathered in the day and decide what we need to keep and what we need to chuck. We also make our own memories. We think what happens is that we experience memories as a side effect of making our memories that occurs during sleep. We’re arranging our experiences into a useful way to store them efficiently in our heads.
