my best friend (or the Universe) left me a clue. After she died I opened a random page in a random book to see this picture
https://en.wikipedia.org/wiki/Ginevra_de%27_Benci
looks exactly like her.
Also somehow I ended up at a place I used to live in Alexandria...it was very eerie. That was before I knew for sure I had a past life there.
As far as solid physical clues for me...none that I can think of
