I am 28 years old and I have an excellent memory. As a child; I was able to easily recall information in school so I always did well in history. I also could read a book quickly and be able to recall all the details of a plot years later. I could memorize something pretty well on the first try and if I did something in mass repetition I never forgot it. I have OCD so I constantly rehearse memories in my mind; but there are many memories I haven’t “touched” in years and come back to me involuntarily or when I go “digging”. I remember details of conversations I’ve had decades ago with various people and sometimes negative memories that I recall feel so vivid that I almost feel sad or angry again. I also remember how I felt at some times in my past and sometimes even the details of dreams I’ve had come back to me. It’s rare but it occassionally happens. Also when I am trying to fall asleep at night; my mind likes to entertain itself by flooding me with memories. Almost like it’s watching a movie. Many have suspected I am on the autism spectrum as well, but I feel very strong emotional feelings for others so I am high functioning autism if anything. Now I only have an average IQ and I suck at math. I also do NOT have total recall. There are things I do forget both long term and short term but the fact that I remember how I felt 20 years ago about a certain thing or situation leads me to believe my memory is better because of something other than my OCD and autism. I know that people with Hyperthymesia have an enlarged caudate nucleus and temporal lobe. What is different about my brain because I have a pretty good memory?
