Vengeful Elegance
At this point I vaguely remember my friend telling me that if I see something unpleasant to go back. But I couldn't.
One of the men approached her and demanded the necklace she was wearing. It was an amethyst tied around her neck with a thin black cord. Then it went black and I snapped awake.
I was in an odd trance-like state during all of this. For all I know I dozed off and had a very strange dream.
No, I don't think it was a dream. I believe you came out of the trance at that moment because that is when that life ended. I want to ask you what did the man who took your necklace look like? Was he the specter that haunted you?
Souls are funny things. Unlike the body they can travel back in time, forward in time, to other dimensions, and be in two places at once. It is my belief that you weren't just seeing that life, you were there. And that some how being there drew the spirit of your murderer.
If you ever see him again get the help of a qualified medium quick! Hopefully though he is through tormenting you. With any luck he will have moved on. Let us hope that he found enlightenment in later lives and no longer seeks to harm others.
