I also woke up briefly at 4am convinced that it was Saturday. What a disappointment . . .
I probably should have realized it was a dream when I couldn't read the research notes I had taken.
I dreamt this morning that I was going to write a true crime book about an early 20th century serial killer, but I could not remember the killer's name. Like, I *knew* I had done a copious amount of research, but my brain frustratingly couldn't come up with the name.
