I am not certain one way or the other but I had some experiences that make me feel like I have a strong connection to the Civil War era as a woman of means.
I took some plantation home tours many years ago and during one, I was halfway up the stairs, following the tour group, when I had an overwhelming feeling of deja-vu. I actually stopped, looked down, and saw my clothing as period clothing from the 1860's. Full skirts and everything. I remember feeling the need to center myself on the stairs and lift my skirt to proceed up the stairs. This weird episode lasted for about 20 seconds then I "snapped out of it", for lack of a better term, but I felt other similar rushes of deja-vu as we toured this home and saw the original furnishings, etc.
Now, my family has always joked that I was some entitled rich lady with servants in a past life, due to my current tendency to try and get other people to "fetch" for me.
It's embarrassing but I admit it is true.
Another thing that made me consider the past life possibility was when I had my firstborn son. When he was very little, he would put his hands on the television and cry big fat tears every time I watched something that showed civil war soldiers or slaves. He could never verbalize to tell me what was wrong but he would get very upset, and keep both hands on the screen and look at me like his heart was breaking. I am not talking about violent movies or shows about war.. more like documentaries about this or that soldier or slave (PBS stuff) with a drawing of someone up on the screen. Now, at 20, he knows all sorts of things about the Civil War in particular, military type stuff that I have never encourage or taught him.
Not exactly past life related, but he also told me that he chose me as his mom... and he also clearly remembered his birth in his early years (but not now). He had a very traumatic birth, and when he was very little he used to tell me that he "couldn't breathe", that it was dark, and that then "they cut me out of you and it was cold and bright".
He doesn't remember this now (he is 20) but he does remember details about a car wreck I had when he was 10 months old, and would tell me the details long before he was old enough for me to have talked about it in front of him or shared details with him myself.
