I feel like you got in contact with your soul there.
The following is what I believe: We are incarnated here to work through our karma. What we did in past lives to and with others or in general.
Generally, we all are incarnated to experience SOME kind of lesson. It doesn’t necessarily need to be living in poverty or help the disabled. Even rich people have lessons to learn (like humility and temptation, for example).
So I think what you saw there was karma being worked through. Finally coming clear and understanding that what you’ve been through is actually GOOD because it shaped your personality. It made you a better person in the progress! That’s probably also why it made you so emotional. The deep connection with your life path, which this is certainly part of.
Or so I think.
