Something similar happened to me a few nights ago. Except the dream character was like, "Something really terrible is about to happen to me, and since my continuity of experience is assured by real-life Maia continuing to exist, I'm okay with the personality part of me dying. (Proceeds to commit suicide by trying to wake up)"
In the style of Jeff Foxworthy's "You Might Be A Redneck If..."
If you're waking up and the characters in your dream start asking you to stay asleep a bit longer because they're running on your brain and they don't want to be consigned to oblivion just yet... you might be on LW too much.
Happened to me this morning, it was kinda weird, and I felt kinda sad. In fairness, it might just be my subconscious brain telling me I need to get more damn sleep.
Anyone have similar stories?
