one second, if the “vision” is true or false does it really matter? What is the harm in doing t’shuva? Why do ppl. say “well, how do i know it’s true? why should i believe it?” Pretend it is even if you dont believe it and use it as a wake-up call. do you really think ur t’shuva will be for nothing?
this is what we call “bechira”. you can choose to believe it and work on immproving your ways or not. once mashiach comes and reveals himself there will be no more bechira and thus one can no longer do tshuva. Just something to think about
