When someone's phone rings and you think it's yours because it's the same ring tone.

dopplefanger 

1) The exact look-alike vampire version of person. NOT an exact mirror image version because vampires have no mirror image.

doppleginger 

an exact look alike of someone, but in ginger form. Usual traits include hair as red as the flaming sun, freckled face, and can also include skin paler than that of the glittery Edward Cullen.

Mr. Robers, I regret to inform you that we have discovered you have a doppleginger, and will no longer be able to be your cellular phone provider

Dopplerganger Effect 

The effect of someone looking more and more like you as they walk towards you, and then less and less as they walk away.

I thought I saw my twin walking towards me, but I was just experiencing the Dopplerganger Effect.
