People tend to carry over trauma from previous lives in the body and in irrational fears which can lower their vibrations reducing their sense of fulfilment. Birthmarks and scars are common to carry over and can be cleared and understood from a metaphysical aspect. Imagine being blind and seeing in a past life, or being able to visit different countries and generations without leaving your own home. A past life can be very real and you take on and re-experience that different body and life experiences.
