Why do we dream and what physiological purpose do dreams serve?

Dreams are like stories our brain tells us while we're sleeping to help us learn and remember things.

When you sleep, your brain is busy working hard, just like when you’re playing with your toys but not looking at them directly. Your brain takes all the events from your day, like that big fight with your brother or that fun game you played, and turns them into dreams. These dreams help you understand what happened and remember it better, kind of like how a photo helps you remember a special day.

While you're dreaming, your body is also getting ready for the next day. Your brain sends messages to different parts of your body, helping them rest and prepare. It’s like when you take a nap before going on a long walk, you feel refreshed and stronger afterward. So dreams help your brain and body stay healthy and ready for new adventures.

Dreams are not just fun, they’re important work your brain does while you sleep!
