I am curious if anyone has come across the idea of womb twin survivors. My mom was too tiny to carry two babies so, she had a miscarriage of I guess my brother early in the pregnancy. My parents even recalled me talking to my brother when I was playing and very young even though, I did not know what happened consciously. It was odd growing up and being fascinated by boys who looked like me or a friend who had the same birthday as me. Learning about it has helped me to an extent make sense of things, but still hasn’t changed how the experience molded my behavior.
Here is a video of if anyone is curious:
