It's easier than that. PhotoRead a thriller that night. See what shows up in your dreams. If you do have parts of the storyline showing up in your dream you have 2 interesting experiences to consider.
Being tired is as good a time as any to PhotoRead.
PhotoReading works how else could any part of the story show up in a dream from a book you haven't manually activated yet.. 
I found being tired worked just as well for PhotoReading but the books became part of my dreams. If I don't plan to do any dream studying I avoid it just beofre sleep. Tired or not.
