Answer 1

There’s research that has shown that memories can be passed down through DNA.

I’ve seen it theorized that that is why we have nightmares about wolves and such when we are children even if we’ve never seen or heard of what a wolf is, it might be that our ancestors passed down that instinctual fear of wolves through our DNA.
