How about these
"When I was about 3 or 4 I would tell my dad stories about how I was good friends with his grandfather. I provided names and traits that had never been said around me before. I also claimed to have ghost brothers who were buried in a cemetery we often drove past. "
"That's kind of crazy. My daughter just keeps telling me about when I was sick she would take care of me, and when I was crying as a baby she would give me a bottle. I realize it's just her imagination (I think), but it's still enough to creep me out."
"My 4 year old daughter keeps telling us stories of her (non existent) brothers-she had a big brother who was eaten by a bear on a camping trip. The worst one though, is when she talks about her little brother who fell into a lake. She's my oldest child, and I only have girls. I have no idea where any of it comes from, but her talking about the little brother in the lake really gets to me. "
"My sister did the same thing. She would tell stories of when she was a big girl and then describe these super detailed costumes and settings. My mom decided to ask my grandpa about it, and after a bit of research, they found she was describing clothing from the late 1800's and a Swedish village that my family is from. She said she played piano and had a dog there. Freaky stuff. She doesn't remember it now. "
"My older sister was born the year my Dad's mom died. According to my dad, as soon as my sister was old enough to say the words, she said "I am your mother.""
"I joined Reddit JUST so I could share this! When I was 9 years old, my aunt had a miscarriage. During my teenage years, she had two children who were 4 years apart. One day when her oldest son was 2 or 3 years old, he said to her "Are you happy I came back, mommy? I went to heaven but you were sad, so I came back to you." I get chills to this day just thinking about it! "
