Eli5: Why/how do we not pee in our sleep?
gpt
Because there are certain things our body does automatically (like breathing) and peeing or not peeing is one of the things we learn to control. Despite being asleep, the subconscious part of our brain stays active. So, it reminds us to keep our pee inside. Unless you really need to go and your brain won't wake up. Then you have the toilet dream.
