@mcc @nazokiyoubinbou I think you could do this with time travel into the past, too. Or, at least, time travel from the future to the present. If the person you will be in 2040 were to travel back to 2025, and were to inhabit your body, what would they think and feel? Let those thoughts and feelings take you over, and guide your actions. (You need to remember to do this on the other side, in 2040, but only for a moment.)
