I used to get loud random thoughts in the hypnogagic state as I relaxed. Random stuff, like "how much are you selling the oranges for tommorow" and "shut the barn door now". Like my head was a radio picking up the area's random activity.

Once, I saw a poster for the film Pulp Fiction, and it caused me to think about the scene where they are saying the N word loudly (i didn't like the scene, it was just stuck in my head as it shocked me). When It played in my head, an old black lady looked up shocked at me.
