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 think I remember something like someone was talking to Dawn (Tara or Willow? not sure who it was) about that poltergeist-thing in the end of the episode and saying that it also could have been really the ghost of Dawn's mum giving them a warning for the future.
Now I really think I have to rewatch the serie again. :)
What season and what episode was it again?

7th season: Conversations with Dead People.

It's, I think, on the second CD in my 7th season set.
