This dream was inspired by me reading some of the book 11/22/63 before I went to sleep.
This dream was a combination of dreaming, daydreaming, and thinking.
The character George Amberson (Jake Epping) was the main character of the dream, and he was spying on Lee Harvey Oswald, who was about to make an assassination attempt against Edwin Walker.
George (Jake) was also thinking and daydreaming about the situation, I was able to see and hear his thoughts / daydreams.
I was also thinking and daydreaming as well, so my mind juggled following both of our thoughts / daydreams.
