heard of? I had a vivid dream about 3 siblings, that had apparently died (they told me this in the dream). One of them told me that she was my half sister, and she seemed to be much older than me. The other two were my full siblings (a boy and a girl). The boy was very close to my age and the girl was a few years younger than me. The next day, I told my older (living) sister about the dream and she told me that years before she was born our mother had had an abortion with what would have been our half sibling. She also told me that she had more abortions before and after I was born. She wasn't sure exactly how many. I just thought that it was weird that I had this dream about about these people telling me that I was their sister and then to find that out.
