In the beginning when she asks if it's possession or regression, I think the translators meant to put possession or reincarnation/transmigration.
1. Possession is when a character inhabitants another person's body; because they are not the same person by any means, the possessor doesn't retain the possessed's memories, just their body and maybe their body's muscle memory at best.
2. Transmigration is similar to possession, but as there is more assimilation in some manner, the transmigrator gains some or all of the person's feelings/memories but can tell that they are not their own.
3. Reincarnation is when the person has fully died and gets reborn into another world or same world/different time. There's no other person to possess or transmigrate into as, since birth, the reincarnator was this person the entire time, they just also likely have memories from a past life. Outside of the isekai genre, Transmigration and Reincarnation are related concepts that both describe a soul moving onto the next life after death with reincarnation specifically being reborn fully as another human, while transmigration is about being reborn as anything. However, within the isekai genre, these are different concepts.
4. Regression is when a person dies within their own world and has time reversed back to a previous point within their life. They have not technically died since they are now alive and younger to some degree, but as you can see, this has nothing to do with the other 3 major isekai tropes listed above.
This is why I was like "if the MC knows about this world from a novel and not her own experience, then she can't be a regressor." Meaning that the translation was meant to say either transmigrator or reincarnator. Likely the former rather than the latter since a possessor and transmigrator both do not really see themselves as the person whose body they are in.
