Why do we dream every night, and what are their functions?

Dreams are like movies your brain makes while you're sleeping, and they help you learn and remember things better.

Every night, your brain is busy working hard to sort out all the stuff that happened during the day. Dreams are like little helpers in this process. Imagine you have a toy box full of different toys, sometimes it's messy, but when you play with them at night, your brain tidies everything up and remembers where each toy goes. That’s kind of what happens when you dream.

Dreams help your brain store memories. Think of it like writing down notes after a big game, your brain is keeping track of all the good stuff you did or saw during the day. This helps you get better at games, schoolwork, and even playing with friends!

Sometimes dreams are funny or weird, but that’s just your brain having fun while it works hard to help you learn and remember things. Dreams are like movies your brain makes while you're sleeping, and they help you learn and remember things better.
