Well, to a certain extent, does it matter? If you personally don’t have any memories from past existences forming these relationships, the information is just a footnote in your life, you put it to one side waiting for verification at some point. The way gnosis works, what you thought you heard may not be what they meant anyway, so it’s not really worth acting on until you have more data.
Lots of people have presentience, this is a human psychic ability, and I would say you can take the credit for yourself for this. It doesn’t need to be related to your UPG about relationships with entities.
This is a common problem for those understood in the astral to be able to see entities… For this, set boundaries called “wards”, and get tougher of those who ignore the boundaries or push them. If you send a message that you are not to be bothered and crossing the line comes only by invitation, then it will be respected.
Setting good boundaries and having strong psychic defenses is also a basic for an occultist… here’s some more on that: 
With these under your belt you’re in a good position to explore and know how to deal with most issues that come up.
(Unlike the lady in the video, beset by parasites and having no clue how to understand or deal with it. Hint: fire does the trick. NOT giving them the credit and power that she does, not calling them masters and believing them is a start. Humans are ridiculously powerful, so we are tricked into feeding lesser entities. They are using her own human power against her and she’s letting them. She is also protecting them. That happens when they get very embedded, she has to get them out no one else. No it’s not a god, she elevates them to ‘god’ to protect them with her own belief. Don’t be like her. It’s completely unnecessary.)
I will also mention, on the topic of parasites getting embedded, when you have ones from childhoos especially they can become so interwoven with multiple subtle bodies and multiple time points and aspect of your being, that i’s very hard to get rid of them. Speaking from my personal experience, it ends up being like you attack and even kill them not once, but again and again until you root them out of your entire system. They will retreat and hide from you, they will sink into quite places inside you you didn’t remember existed, and wait you out. Really stubborn parasites are not to be taken lightly, even though they are weaker than you, they are cleverer than you, and unlike you their life depends on winning, so they fight harder than you. A real embedded parasite exorcism is not a one and done. Mine took me six months or effort being mentored by Samael to finally resolve every last bit. And I was nowhere near as riddled as she is, I had just one, and I wasn’t weakened and sick. You really want to get them out before they make you sick: the weaker you get the stronger they get and there’s a point where you probably lost and can’t win any more against the discrepancy. That’s why it’s such a basic to always stay on top of.
