As of Motel California, the Darach put wolfsbane in the coaches whistle so Derek, Ethan, Isaac, and Boyd could suffer from hallucinations.

So i'm wondering how exactly did the other hallucinations happened ... the girl in the woods, the girl in the basement of the house, and probably the dead guy at the pool suffered from one too. They weren't werewolves ... how did their hallucinations happen then??????
