Is there a "why" do the skins exists?
So, I was reading a few discussions here, and started to link as well these short descriptions the skins have. We know so far they have a lore behind related to certain life episodes of each character.
Now, my question goes beyond that. Is there a reason why skins exist in the entity real as it is?
To put up a theory for example, maybe the entity dragged several versions of oneself to the realm? Like, Meg on her default skin, Meg trying out the dress her mother gave her, and so?
I haven't read the whole lore yet in the game so I'm not sure if it mentions something like that among the tomes.
