Alters with their own life memories

Hello, hope everyone is doing good.

This is more of a question than just a topic, but we'll give an idea of what we're talking about.
It always happened in recent and non recent years that we have these sort of flashbacks, seemingly out of nowhere, that makes us "see" with our mind's eye various places, people, etc. that we are sure we never saw in our life. We found out this happens the great majority of time just with three of us, specifically the Guardian, and Rebecca and Viola. They have very different fashbacks, meaning that they "see" different places, different people, and even seem to have lived in different time periods.

Since Rebecca's and Viola's flashbacks are not clear to me (because they're not out that often) I'll discuss Jason's (the Guardian) ones. He doesn't clearly remember the life he had, but he "remembered" some things through these flashbacks. He knew he was exactly as he is in the inner world now, a 40ish year old man, glasses, and nordic appearance. He remembers a house near the sea, in the north of Europe (we're thinking that the place might exactly be the country where we are now), maybe in the 90s. He remembers he had kids, probably both of them were boys. One of them had freckles and long hair. For this reason, whenever we see a kid that looks like that, he instantly (when out) gets taken back to his "old" house, and feels like he's looking at his own child. He doesn't remember having a partner, probably because he wasn't really fond of them in the first place, for some reason. But he was married. He also remembers what he wore, what was in his closet and what he liked to buy. For this reason, when we go shopping and we see something similar to what he "wore", the same flashback thing happens again very vividly. He remembers the walks on the beach near his house, and remembers his bathroom for some weird reason, and how it was decorated. He remembers being with other people, reading, and driving a car.
There are other things but you get the idea.

The thing is, he knows he's not there anymore, and he genuinely doesn't remember and doesn't know why this happens. The feeling is always a very weird one. It's like he died at a certain point, and he's now a sort of ghost entity in this mind (which maybe has to do with the fact that he considered himself an angel at some point?). But he doesn't consider himself a ghost, he feels like and knows that he's living right now as a part. But at the same time it's like this is a sort of past life, and he's very melancholic and sad when these memories reappear because of some external trigger.

With Rebecca and Viola is sort of the same thing, but in the 1950s. All three of them don't remember anything clearly, or spontaneously. There seem to be certain triggers in the external world that make them remember what they forgot. For all of them it seems like a past life. This is very strange for all of us.

Do some of you have similar experiences or have ever heard of something similar?

Yes we do. One of these supposed past lives I tried to research and it actually checked out for as far as I could access records for free online. We have 'memories' of past lives of at least 3 of us. One died a soldier in a train wreck on his way home, and left behind a wife and small child ( the one I researched). He always told me an exact date and it exactly checked out. January 3 1917.
One got shot in the chest. And one used to live in London somewhere long ago.

We have such memories as well, I can't explain it well in a scientific way but they are something like.. past lives? I believe it, somehow. If you need to talk a little about this, just pm us. :3
