I recently have been thinking about my childhood as an adult and remember my brother and I having encounters of dry humping. I was 7-12 and he was 9-14 yrs old. It started out confusing to me and then I became uncomfortable with it and remember feeling fearful when telling him I didn’t want to do this (not sure why). When I think about the fear at this time, a flashback comes of me being held down by my wrist, naked and anger (as a child), I am not sure who is holding me down. Also my wrist starts to hurt in real life and I often start to gag and almost throw up when this flashback occurs. How do I know this flashback is likely real? And if it is likely real how can I find out who is holding me down? Would this having anything to do with my situation with my brother when I was younger?
