Ghosts?

Do Abigail’s cronies think that they can truly see spirits? Does Abigail really believe that she can see witch’s spirits? Mary Warren seems convinced that she could see spirits, this much is evident when Danforth examines her. She claims that she could faint because she thought she saw spirits. If Mary Warren was not thoroughly convinced that she could see spirits, she would have been able to faint on the spot and provide solid evidence to Proctor’s claim. It is never clear as to whether the other girls think they see spirits or if they just follow Abby’s lead. I think this depends on whether Abigail believes she sees spirits or not. In the first act, she knows she is faking it. But, it seems that in act 2 scene 2, and in act 3 that she truly believes in her “ability” to see witches. She takes the bruises and cuts she could have easily made herself as proof. It is never perfectly clear that Abby believes she sees spirits or is acting this way to convince Proctor that what she does is legit. I however think that she has played this game for so long, that she has started to believe her own lies.
