I have trouble sleeping and have tried a number of different things. Last night I had decided to visualize the woods with a darker path leading into the woods and fireflies. I was looking at that scene from the porch thinking how peaceful it was and that it might allow me to drop off to sleep.
Later when I tried to picture that scene, it was just totally black. I was trying to bring up the scene and all of a sudden I had a picture in my mind of colorful lego-looking animals standing in a line like chorus dancers. Where did that come from? It was not what I'd intended to visualize!
