Doppelgangers

Hi everyone.
Today, I read something about Doppelganger. It made me half horrified and half amused. A Doppelganger may sound really unfamiliar to most people, but in actual fact, a Doppelganger is actually what we known as our own soul-'ling hun'.
Aiyah, I know its nothing unusual, but I really got nothing to do online. After researching, I've found out that Doppelganger means "double walker". It is like a shadow-self that is supposed to accompany every human being. Dogs and cats are said to be able to see those.
There are certain mischievous doppelganger are able to make themselves visible to a person's friends or family members while the person is apparently not around. You can call it a ghost or spirit, but a doppelganger don't harm. However, it is bad luck if you see your own doppelganger.
Do you know Queen Elizabeth saw her own splitting self-image (Doppelganger) and died shortly after ? Hence, by seeing your own doppelganger is very dangerous. It certainly only means bad news if you see your own doppelganger.
So, be really careful if you see someone who really look like you.

My own Doppelganger is the last thing I want to meet in life.
