When I was about 12 or 13 my mother had a cancer scare and had to look at the medical records from my birth. In the records it is shown that there was a still born baby, I was supposed to be a twin. The doctors never told my mother and she never saw it in any ultrasound, they told her what she felt was an extra placenta. Since before then my family has seen a girl with my face.
When I was a child I slept in my parents bed until I was 6, the last year I slept in there, a girl more like a shadow, would stand at the end of my parents bed and stare at me for what felt like hours and then she would slowly walk into my parent's bathroom. I moved into my sister's room after a year of that and I haven't seen a spirit since then.
My father has seen her in the bathtub in the master bathroom. He believed it was me and immediately left the bathroom only to see me in the kitchen, when he went back she was gone.
My older brother that slept in the basement yelled at me for shaking him awake in the middle of the night for a month straight. I never did that. He said a girl that looked exactly like me, he thought it was me, shook him awake saying "TJ wake up! Please wake up! TJ!" He was angry of course and yelled at her "get out of my room!" He said "I" got sad and slowly walked up the stairs but he never heard the door open or close and when he looked no one was there. He started sleeping upstairs on the couch for a while.
My older sister asked me why I went into her room in the middle of the night and kissed her forehead. I was sound asleep in my parent's room.
My 4 year old niece insisted I went to a movie with our family and when I told her I was at the mall with my friends she casually said "ohh so it was the fake Emmy?" I was shocked I asked her "who?" she then explained calmly that "there's a girl and she has your name and your face with long black hair (my hair is naturally black but I have it dyed dark brown) she was at my birthday party" I asked her "what was she doing there?" She then explained further "she was wearing a white dress and she knew Charlie's (my younger brother) name, she kept calling him 'Charlie! Charlie!' But he couldn't hear her." I had no words, no one had ever told her the stories of a second me or that I was supposed to have a twin. She promised she wouldn't talk to her "when she comes back" because she knows that it's not the real me.
My brother in law refuses to stay the night in my parents room because he saw her, wearing a white dress and a cross necklace, standing in my father's closet. I was out of town when this happened.
Many in my family have the gift to see those on the other side, I am not one of them. What I fear is that one day I might come face to face with her, I am afraid she is not who we assume her to be. I don't know if she is my twin or what I fear most, something evil taking on the shape of the child my mother lost. My house was built in the 1970s no one has died here as far as I know, but things follow and feed off of members of my family and their energy. I once tried to figure out who or what she could be or what they want (there a many spirits in my house) my dad begged me not to, because when you seek something out you might actually find it. What could it be?
I've heard some stories where they'll try to kill or otherwise take the place of the person they look like.
However i'm more curious about how didn't the doctors tell your mother they noticed another fetus/baby in ultrasound or something, even before they found out it was stillborn. That might sound minor, but it's also a big question you shouldn't overlook.
