Dream diary

A dream diary is like a book where you can write down your dreams that you have while you're sleeping. You can write down what you saw in your dream, if it was scary or happy, and any other details you remember. It's like keeping a picture of your dream in your diary so you can remember it later. It helps you remember your dreams better and understand them more. Plus, it's a fun way to keep track of all the cool dreams you have!
