Does anyone ever feel a moment happening twice in life?
Yes for certain, dejavou is one and means "already seen" but I've had many an experience that reminds me exactly of an incident that happened before, in a slightly different way. Often I'll catch someone trying to be manipulate and I know their "trick" and may let them think they are clever. I've had it in relations with others who do something I've lived through before. The question is, is it worth going through again with the outcome being very likely it's the same.
Same with studying or teachers. They will utilize the same techniques and if you pick up on it it is easy to know that they want to get you to learn and think about the way you have already made judgments on a topic but want you to challenge it.
It happens as life is so similar, even with music I've had improv moments that are so similar I already know what to do next even with no plan.
Odd stuff for sure.
