Full disclosure, I am writing a paper about Suspiria, but I am having a hard time finding a certain theory about the film in writing.
For a long time I've known of a theory that Suzy herself is a witch but in wanting to explore that I've not been able to find much documentation or writing about that interpretation. Recently I watched the visual essay "Do you know anything about witches?" by Michael Mackenzie, on the 40th anniversary Blu-Ray by Synapse Films, and he too mentions this theory that Suzy could possibly be a witch.
So does anyone here have any knowledge of this theory, and more to the point, a written source for this theory online somewhere?
A group of college kids are en route to some sort of vacation getaway (spring break maybe?) and they stop for gas but the gas station is old and broke and the killer dude is inside. Essentially it’s just a straight slasher from there where the killer picks me off one by one. At one point they do get the killer in the trunk of a car I believe.
