A poltergeisty First?

[dragonyphoenix]

So I'm watching Conversations with Dead People in which both Dawn and Willow are visited by the First except for Dawn's visit there's this whole poltergeist thing going on. I thought the First had no physical aspect, which leads me to wonder how the poltergeist effect came about. Has anyone seen this explained?

I always thought there was a real demon that Dawn was having to cast out here, either an agent of the first who was helping it make a convincing show of pretending to be Joyce fighting this demon to get to Dawn, or a good-guy/non-aligned demon who was trying to stop the first from manifesting to her as Joyce.

I like the agent of the First idea better. It makes more sense to me.
