Interesting subject. Europe (and the rest of the world) is full of places that have been inhabited for millennia, it’s not surprising that descendants of europeans transplanted elsewhere and going travelling in the ancestral homeland have strong emotions and feelings of de ja vus. I think it depends on your cultural background where you will feel this.
I myself have experienced it as well in my travels and its a powerful experience.
My family is of Dutch, English, Maltese and eastern euro slavic descent (polish and ukrainian). When I have visited in Holland, England and France it’s evoked those kind of emotions in me. Difficult to describe.
I’m also a big history buff and visiting these places that ive read about for ages is very exciting for me.
All of us have huge ancestral trees which grow exponentially as you go back generations and centuries. This includes people from a wide variety of backgrounds, cultures, and social classes. We all have had slave ancestors for example, somewhere back the line. Some few have descended from nobility, and all from free folk.
The relatively new science of epigenetics is fascinating, because it is now known that we all carry genetic memories from our ancestors, and I think this is what we are feeling.
Another tidbit, the first woman I was intimate with was very spiritual and aware, there were a number of things that she said that were really shocking because there was no way she could have known otherwise. But one thing she said stuck with me, that we’d been together in ancient Egypt...
Personally, I do believe in reincarnation. We have had many lives, in many different contexts, all learning experiences, and we all go back to and come from the source, the one. ‘God’ if you will.
