I can't say I've ever seen a Doppelganger. However some of my family members have.
2010 - at this time the family members residing in our home were: Our oldest daughter and her husband, our youngest son, and our youngest daughter.
My husband saw the first one sometime in 2010. He came home from work at midnight. I was asleep on the couch in the living room. He was on his way through our room to the bathroom to take a shower, when he saw our youngest daughter sitting at my computer. He called out to her. She didn't answer or even move. He assumed she had earphones in and didn't hear him. He realized he had forgotten to grab a towel from the laundry room so he turned around and headed that way.
Our bedroom is on one end of the house, the laundry is on the opposite end. He walked down the hall, through the dining room and kitchen. Just as he was about to open the laundry room door, M (our youngest daughter) stepped out. My husband asked if she had just been on my computer. She said no she had been in the laundry room.
We all picked at him about getting old and seeing things. That's before I did some research on Doppelgangers.
Shortly after my husband saw our youngest daughter's Doppelganger, our youngest son saw mine. This happened about 6 o'clock on a Saturday evening. I had just finished cooking dinner and was waiting for my family to come home, except for our youngest son Z who had gone into work about an hour before.
I decided to do some laundry while I waited. I always had to keep myself busy when I was home alone. I still had the notion that if I was doing something there was less of a chance for me to encounter anything ghostly. Plus, staying busy made the time go by faster. I was in the laundry room with the door shut when I felt or maybe heard someone come into the house.
(As a side note: there is absolutely no way anyone could ever come into my house without me knowing it. Whether I'm awake or asleep. When our kids were younger they use to try to fool me. Never happened. I can feel the least change in air pressure. Drove them crazy.)
I asked, "Who is here?" Z answered me and said his new manager sent him home to shave because he had a 5 o'clock shadow. He was fussing about it as he went down the hall into the bathroom.
I stayed in the laundry room folding clothes. We have never kept our clothes in our bedrooms. I have a huge laundry room so everything clothing wise is kept there. Oddly enough I was folding Z's clothes when I heard, "Mom, why are you putting those in my room?"
I opened the laundry room door, walked out into the kitchen just as Z walked into the dining room from the hall. The look on his face frightened me. It looked as if he had just seen a ghost. I watched as all color drained from his face. I asked him if he was ok. He just stared at me. After about a minute he snapped out of his trance.
The following is what he told me: He was standing in front of the bathroom mirror shaving when he heard a shuffle. He looked up and out the door. He saw me dressed in a red robe walking really fast, holding a stack of clothes. I entered his bedroom so he stepped out of the bathroom to ask me what I was doing. I didn't come from the direction of the laundry room, I came from the opposite end of the house from the other bedrooms. His is the first bedroom in the hall before you get to the bathroom. I did own a red robe at that time; however, I was fully dressed in jeans and a t-shirt. Nothing red.
Before that day Z was a non-believer of the paranormal. For years He swore he still was, he refused to talk about that day. About a year ago he and his wife bought a house built in 1940. He's now coming around to the fact that there are some things that have no other explanation.
Last week (April 22, 2016) my oldest daughter was visiting. She and I were laying on my bed talking. I fell asleep. She got up to get a drink from the kitchen. As she was leaving my room she saw M's (youngest daughter) boyfriend coming from her bedroom which is directly across from mine.
She said he had a faraway look in his eyes. He was laughing as if something he and M had shared moments before was extremely funny. He walked down the hall into the bathroom and shut the door.
S continued on to the kitchen. She got her drink and started back down the hall. As she was right outside of the closed bathroom door, she noticed J was stepping out of M's bedroom. He looked as if he was half asleep. He asked her if someone was in the bathroom. To which she replied, "You". She reached over and opened the bathroom door, it was empty.
