Ancient Wisdom and Pagan Spirituality

PLR is wonderful for stress and can have physiological effects on the body as well. One of my first regressions was to what I believe was the battle of Hastings in 1066. I left my home, a farm to go to a battle, arrive and was killed almost immediately by a flaming arrow or spear. With my wife's help I changed this into remembering to make and take a shield with me, surviving the battle in my minds eye.
I had been suffering from unstable angina on a daily basis before this regression. After the regression I didn't have an angina attack for over 6 years.
Is it real? Do I really believe that I changed the past? All I really know is that I stopped having angina attacks and weekly runs to the hospital for a very long time.
