I have both false memories, which is common with PTSD, as well as a very inattentive/uncaring parent who frequently claims to not remember things that definitely happened. I also have this vague memory of my childhood dog's last puppy of her only litter to be adopted out, including his name and several accurate details about him all of which have never been discussed with me directly and I didn't bring it up until I was a teen. But I was slightly younger than a year old when he was adopted and some of the surrounding memory is fairly dream like which has left both me and my father at a loss for an explanation of why I have these memories that he himself can hardly remember.
