I have read testimonies of people who did receive replies from saints prior to fulfilling a prayer and they requested certain things some times (like correcting one aspect in one’s life - the saint knew about it since they are in Heaven, or donating to a certain church). Or a story when Virgin Mary answered something like “why do you say we do not help you?” prior of fulfilling a request.
I would like that, having an interaction with them, much better than just to help me with what I asked.
