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?

That's what I figured.
