Exorcism by Zerbert? Is "Prophetess" Mattie Nottage Zerberting Demons?

It's possible "prophetess" Mattie Nottage may be zerberting demons, something potentially learned by watching The Cosby Show. (You can watch the scene here if you do not have a frame of reference for the zerbert.) Here are clips from a recent exorcism video she released.

It's hard to discern if she's actually making the zerbert noises or if those were edited in for dramatic effect. This "exorcism" is more about drawing attention to the false prophetess, than it is about setting someone free from demons. 

Here is the disaster in unedited long-form.
