I really can’t imagine any subjective difference between having free will and not having free will. For example, “Observing myself act in ways I never intended to act” seems to be the conception we have of free will from video games/movies/etc. (e.g. in Dragon’s Dogma, your pawns can get possessed by a dragon and then they run towards you trying to kill you while telling you that they’re not in control of themselves) but I don’t think we should generalize from fictional evidence.
