I had this dream recently in which, unbeknownst to me*, someone was playing a deeply unfunny prank on me that involved men pretending to hijack the bus I was on.
I say unbeknownst (asterisk) because, of course, it was my dream. Everything in it should be completely beknownst, because I was making it all up. But the subjective me in the dream had no idea what was going on, or thought it did. [The complete dream, in which I dared armed men to stab me to death, is here.]
This video examines the duality of the brain's hemispheres. It doesn't fully explain what I experienced but it offers a suggestion, as well as a rather unsettling vision of how the mind works.
