I would suggest that you spurn their advances and claims to be family. They are not to be trusted (so I am told).
I don’t do a lot of reading (other than FR) on this subject so as to not adulterate what I’ve seen myself. Given that, have you ever heard of these things (whatever they are) claiming to be family or related? It felt like it considered me its child. I was five years old, so I can’t rule out it just being a dream.
