I find that my dreams have change as I got older.
I use to have dreams of having to go back to college or even High School. Recently, when I have these dreams, the action would stop and I would realize that no one would care about something that might of happen so long ago.
I have mix feelings about losing these going back to school dreams. Though, I did not care for the anxiety of not passing, I did enjoyed reliving my school life. School for me was a time of the pure enjoyment of learning and low stress.
When I retire many, many, years from now, I plan to go back to school and spend my days doing research.
