Some appear to glow or emit light type optical energy. Some are smooth and appear to glow from within. Many of these markings have been documented. Some even appear to change direction and or location over a short period of time. My research has shown me that these are not the same as the reported U.F.O. E.T. Alien implant area scars.
Implant scars do appear very similar to some symbols of skin writing.
Implant scars last forever but skin writing can sometimes disappear over a short period of time. This is a major difference in events. I have had a personal event with skin writing. My experience with this phenomenon is quit different from most. I believe this might also be a mental or mind over matter psycho kinetic type phenomenon.
