I dunno about 'that' life. I can tell you what happens to me.
When I am puzzled by who the heck this person is to me..I keep it in my mind.
I can talk about reincarnation to others, read books, novels about past incarnations of others...
I mean keep it like a burr in your saddle.
(I watch Yellowstone, lol)
Suddenly, when you least expect it it may come to you, as whole scenes come to me.
I dunno, it's worth a try.
Also, after many hours of meditation suddenly it's like my eyes have opened (inside, ha), again to a 'scene'...oh my...it's like being there!
So far it hasn't happened while driving!!!
