There have been some very dramatic cases on record of people dreaming about what appears to be memories of a past life. However, you first need to research the information in your dream to see if it's a possibility. I have many problems with what you have dreamed.
To begin with, I don't believe that even a lady of royalty would have been wearing red velvet in the 1300s. The color red was made from red dye that was extremely expensive to buy. It costs so much?
Whole families were supported by selling it. The pictures of that time might show a king wearing red or patches of red, but it was most likely a color that was reserved for the king alone. My other problem with your dream is that no lady of royalty would have found herself on a battlefield of warring soldiers.
Such a thing is unimaginable. Enemy soldiers had to battle their way into a fortress that was built to keep the royal family safe. There was usually a castle and an entire village that was completely walled-in.
The village was there to keep royal needs attended to. It also made it impossible to starve the royal family into submission. I can't imagine a knight ever killing what would obviously be a lady.
Such an act would be considered cowardly. Ladies almost never travelled about the countryside in that time, because the dangers were too great. I can think of one exception to this, and it's possibly the only exception.
Royal families often arranged marriages in order to keep the peace between two countries. When the prospective bride had to travel to her new home and husband? A huge company of soldiers rode along to protect her.
However, a prospective bride would NEVER have worn red. It was not considered a suitable color for a virgin. Here is what I think.. I've been a HUGE movie fan for a great many years, and I also love history.
I think what you describe is a pretty accurate description of many classic films. Classic films were never worried very much about historical accuracy, and the "lady in distress" story was a favorite of Hollywood. I am not trying to make fun of you in any way.
I'm also not denying that it is possible for people to have accurate dreams of what appears to be a past life. I'm just saying that it sounds to me like you watched a movie when you were very young that made a great impression on you. Your concious mind forgot it, but your subconcious mind never did.
It became a fascination to you, and your subconcious mind has obliged your desire to see it over and over again. You don't have to accept my explanation, however I do hope that will start to study history. Find out if what you dreamed could have ever happened.
If you want to be quite sure of this seek out a hypnotist.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
