There is all kinds of literature concerning people being influenced or even taken over by something outside of themselves. Gypsy curses. Love spells. Possessions. Altered states.
Sometimes, a duplicate of a living person takes form, called a Doppelganger. The double does things the original person is unaware of, but others see.
"I didn't know what I was doing." "I didn't know what my double was doing." (!) "I don't know what came over me." Maybe these are more than just common expressions. Maybe our wills are not always our own. What do you think? Let's write about it.
