1.) That one nightmare I had when I was 9, that was a mashup of Ghost in the Shell, Pinocchio, the Tower of London, and Disney World. Which persisted even after I awoke, in the form of horrifically vivid hallucinations.
2.) Married. Had kids. Grew old. Woke up.
3.) Ever had a series of dreams over several nights with an overarching plot, like some kind of subconscious-based tv show?
Imagine the last episode abruptly ending with NTR.
