2/2 or something behind my back, I was going to bestow it upon someone. It lasted less than a second before I was escorted back into reality. I had other visions like this too, but it was not associated with any of my hearttypes. I don’t really have memories of having been her, so no, I’m not kin. But what else could this mean?
Are you positive you’re not Peridot-kin? because that does sound like a memory of being her.
Other possibilities are you could have experiences a ‘ride along’ or reverse soulbonding event.
That’s when your consciousness is projected into the mind of a fictional character going about their day and you experience them and their thoughts with them as they do things. (the way soulbonds experience the life or their bonders)
