Its strange and interesting stuff, you would wonder why it impersonated your mum.Humans usually have reasons for doing things,mainly to benefit themselves or others,the paranormal doesn't seem to function on that level.
I never experienced my doppelganger, guess it is for the best. But I have had ppl tell me they just seen me like a hr ago lol. I know doppelganger are not very nice. Glad your mom never came face to face with her's
