Hello
@Kenz1010
I am taking the freedom to anwer your specific point regarding the aspect of "choosing" your life prior to be reborn.
I have the clear memory of going through a similar process, although it was in such a specific context that I am sure you would be interested in knowing how I remember it.
I was taken to a specific "location", if I may say. The surroundings were different from all the others I remember in the life between lives, I was "summoned" in a place that felt "higher" by a very wise and loving being, seemingly female. She was, as far as I remember, accompanied by what seemed to be two other male being, but she was the one who made most of the interactions. I felt that the "place" was ..I would say, very cloudy, in a dominance of blue shades.
She explained that she felt it was time for me to go back and start again, but I was at first very much opposed to the idea. I was still heavily influenced by my previous experience that was violent and sad, and I had grown accustomed to being in the other side and found relief there.
She then, in a very welcoming wave of the arm, invited me to look down and there I saw what I think was my life now (I don't remember what I saw, but am sure it is was she showed me), and explained that there would be progress for me, along with what I believe is a good way to close the experience of my previous life.
It is very important to understand that, while I had no choice in choosing, let's say, my exact location (it's not like I had the freedom to pick from a lot of different scenarios), I was in no way forces to go back. I was very positively impressed by the chance she offered me, and as soon as I was hit by the realization that I actually wanted this to happen to me, she smiled and slightly pushed me, I felt like I fell down and it is followed by an intense feeling of being submerged by sensations, and then I have my first memory of my current life.
It is interesting to point out that, when telling this to my dad, who witnessed my birth, he actually confirmed that the colors I saw on the wall, the colors of the doctor's clothes, the position and shape of the window and where my father was standing were actually consistent with the room I was born in.
I also have a somehow odd memory of a vision (that I still remember) of the first meet of my parents. I can see how and in what setting my parents met, and cannot decide wether it is imagination or a vision I was given to see prior to my birth, since I think my father might have told me how he met my mother, altough I am sure he never went in such deep details. One thing he told me, not long ago, and after I had these visions, is that the first time he met my mother, he was hit by this realization "I will have children with this woman".
I find it very beautiful, and frankly very important to my current outlook on life, to know that I was the one who chose to come back, no one forced me even though I feel that it is this wiser female force that "picked" my family. She offered me this beautiful gift and I accepted it.
