However, as somebody who is on the autistic spectrum, I have noted that my index and "ring finger"[edit thanks to comment] are of equal lengths, a trait more common in females than males who tend to have one longer - see https://en.wikipedia.org/wiki/Digit_ratio
Another aspect/theory from personal experience is that my earliest memory was as a baby, equally I used to have a nightmare that abaieted when I was able to tell my mother who informed me of my birth complications and so much of my nightmare correlated, just seemed so related but then, never know for sure beyond once I knew this, my nightmares stopped. In short, maybe (least in my case) autistic people senses and other parts of the brain kick in earlier at a time when we are less able to process them and this becomes another party of the puzzle.
But would I change if I could go back in time and become normal is a question I have asked myself and the answer for me is - no, though the thought of what life would of been like, naturally yields to pondering.
