Something to keep in mind is that Clare has Teresa in her, and Teresa did sense Priscilla's yoki. So Clare has not only her experience as a child, but potentially some faint memories from Teresa as well? Not necessarily any vivid memories, but perhaps some feelings left over from before she died. All Clare brought the organization was Teresa's head, so who knows what part of it they used to infuse Clare. If they used the brain well, yoma gain all the memories from humans when they eat their brains so I could see it working the same going the other way, albeit to a severely reduced effect.
I think that's a good theory. Certainly makes sense to me, at least. (:
