Anyway, Freud says that the rememberances of parents are transferred to their children. Which is why children sometimes find themselves in situations by which they act like their parents. Sometimes committing the same errors, in the similar situations, as they have, though, in a technicality they are completely different people.
Also goes the same vice and versa, that they do the very same beneficial activites as their parents would have. His research showed that it even comes about without a parents influence.
He also showed how a person can recall memories that he himself never experienced but that somehow were transferred to that individual- maybe an inheritance of "family tree".
It may not sound like a normal thing. But I think it is something very worthful.
