I don't think the person you see in your dream is the tadpole. I think they're working against each other. The tadpole wants to hurt the dream persona, or so it seems to me.
Maybe I'm wrong, I don't know. But I'm gonna go out on a limb and say they're different entities, and if I'm wrong, I'll look silly when full release hits.
But for right now, my prediction is that the dream persona is *not* the tadpole.

I also want to point out that the dream persona calls you Chosen in the first dream sequence. That can't be a mistake.
