What is the phenomenon of remembering dreams tied to?

Remembering dreams is tied to how your brain wakes up and pays attention to what it was doing while you were asleep.

When you're sleeping, your brain is busy having all sorts of fun adventures, like flying with elephants or talking to a giant cookie. But when you wake up, sometimes your brain is still in the middle of its adventure, and that’s why you remember the dream.

If you wake up gently, like when the sun starts shining through your window, your brain has time to say, “Oh, I was having a cool dream!” So it remembers it clearly, like when you finish playing with your favorite toy and still think about it for a while.

But if you wake up suddenly, like when someone shakes you or a loud noise happens, your brain might be confused. It’s like getting pulled away from a game in the middle of the fun, you don’t remember much because everything happened too fast.

So remembering dreams is kind of like remembering what you were doing right before you stopped playing.
