What does this mean to you exactly?

For me it means the memories passed down through our DNA and social behavior.

But at a deeper esoteric level, I believe we all connect into a collective unconsciousness where we download memories or fragments of consciousness through historical archetypes. This is why so many awakening people feel that they are descended from royalty or gods and goddesses. Otherwise it does not logically make sense that all the people who feel that they used to be a monarchy were actual monarchies. The numbers don’t make sense unless they were all positioned in different parallel worlds.
