This is going to be a little hard to explain but i´ll try my best.
Several members from my Family (including my girlfriend, who had no knowledge about this) have seen what appears to be a Dark figure shaped like my older brother. This has happened for many years.
Strangely enough, it seems to have started with his wife (who lived in a different country by that time and saw this figure before they even met in person!). The figure seems to be attached to my brother´s wife, since we (except my father and myself) started to see "IT" in our house as soon as she moved in.
I can´t really confirm or deny any of this, since i have not personally seen it. But i know my family, and they would not make something like this up.
The reason i´m kind of worried is because, if it really is a Doppelgänger, i have heard that they actually try to kill and take the place of the person they imitate.
So, what do you guys think about this? ever had any experience with a Doppelgänger or something of the like?
