Doppleganger

Holy cow, I was totes about to head off to dreamland for the night. But then I read something that gave me quite a fright [the rhyming was not intended].
I read about a phenomenon entitled doppleganger. A doppleganger is a spectral counterpart to a living person; similar in appearence, but not alive. For some reason this really made me think of mirrors and reflections. When you look into a mirror what are you really seeing? I once had a nightmare that I was followed by a girl in a mirror. She followed me past everything that a reflection can be seen in, and had I not woken up when I did, she would have drawn me into her world and eaten me. Quite disturbing, I know. It was my dream and you don't have to tell me. I have so many disturbing nightmares, but I need not tell you about them right now because that would be getting off topic, and I am really trying to work on not doing that these days.
So back to dopplegangers [a thought equally as disturbing as my nightmares]... it is said that if a girl stands in front of a mirror on Halloween holding a burning candle in each hand and having a piece of apple in her mouth, the mirror will reveal her future husband's doppleganger. If said girl were to walk around a graveyard twelve times [I can't find specifications on whether or not this is to be done on Halloween] she will actually meet up with her future husband's doppleganger. No thanks, I'm not all about inviting any spectral beings into my life, even if they would reveal to me what I long for most out of this life. This thought is quite terrifying to me and I will be very suspicious from here on out when looking into the mirror. I mean you always expect to see your own reflection in it, but what if you didn't? What if you saw something that weren't prepared to see? I would say goodnight, but uhm, I don't think I shall be sleeping for a little bit. I have a case of the heebie jeebies now.
