My name's Aaron and this happened to my girlfriend less than an hour ago. I found this site whilst looking up doppelganger stuff on Google immediately after the encounter. I'm more or less hoping I can get some information on the phenomena.
I was sitting on the couch playing xbox (which sits looking at the bathroom door, the TV sits on the edge of the wall that leads to a hall which the bathroom sits in the middle of, so from the couch you can see the bathroom) while my girlfriend was taking a shower.
All is normal, she gets out of the shower and asks me, "Why didn't you grab your cigarette off the sink?" I responded with, "I forgot I had set one there" at which point she informed me that I had came in the bathroom and asked to get my cig along with a 7 minute conversation with her while she was in the shower.
I had not gotten off the couch at ANY point while she was in the shower. She is positive it was my voice and says she caught a glimpse of me smiling while she set her hair tie on the sink next to the shower. She heard the door open and close when "I" came in and left but I would have noticed any light as it opened as I'm sitting on the wall you look at coming out of the bathroom. I'm positive it never opened.
I have no doubt she's not messing with me; however, we went on a little amateur ghost hunt in a graveyard not far away a couple weeks ago. I wonder if this could have anything to do with the encounter. And something else I'm not sure whether is related, the last 2 nights I have found feces (poop) in the shower. We do have a cat but I have suspicions that it wasn't him. He's never gone outside the litter box AND the amount seems... Unnatural for a cat, full blown man sized diarrhea.
I'm just hoping somebody could maybe give me some information on "doppelganger" ghost voice imitation or just anything you think I should know given my story.
