My mom dreamed in black and white. The only reason I know this is because I told her about one of my dreams when I was a little kid, around 4. She didn’t know some people dream in color until I mentioned my dream.
In it, I had a purple elephant, and he would put his head on the ground and let me climb on him, and onto his back. Then he would carry me across the lake, go have adventures, and then he would bring me back home. He protected me and let me hide from things I didn’t like. Then we said goodbye, and he went back across the lake. I had a vivid imagination. Adults often called me precocious. I never knew what that meant until I got a bit older and knew how to look words up in the dictionary.
