Very interesting & thought provoking @deep1111! Have you ever thought about inherited trauma, that the trauma of our forefather's is imprinted into our DNA? Therefore should there be any 'unfinished business', things families tend to either whisper about or try to sweep under the carpet, that trauma will not go away and will be passed on to future generations. Look forward to more.
Yes! I read a study concerning mice and "trauma" being passed down generationally in the form of fear, which is an instinct. If fear can be handed down generationally, then in my opinion, forms of fear can be handed down generationally by way of altering instinctual reactionary processes, but you also have to understand that neural pathways can be reconfigured through the ingestion of information. So, perhaps even fear can be overcome in the course of a lifetime through desensitization.
