"April Fool's Day": Was It All a Game? My Crazy Theory

Alright film freaks, AndersonCuts here. Just re-watched "April Fool's Day" (1986) and I'm buzzing with a new (maybe insane?) theory. We all know the big twist — it’s essentially a murder mystery that turns out to be a prank gone… strangely far? But what if it's more than just a prank? What if Muffy (Deborah Foreman) is deeply, deeply disturbed and meticulously stages the entire weekend not just to fool her friends, but also to finally exorcise some kind of... family demon? Think about it. The island's isolation, her weirdly unsettling demeanor with the whole “play-acting” thing, the elaborate props... it all feels too well-orchestrated for a simple college prank. Remember the scene where she finds the “dead” Nikki (Deborah Goodrich)? The way Muffy laughs is unnerving, almost hysterical. It's the laugh of someone barely holding it together, not someone relieved the joke worked. And that final shot of her in the theater – alone, acting out all the roles – chilling. I'm betting it's all hinting at a much darker backstory that the movie never fully reveals. My wild theory is that Muffy suffers from some serious trauma related to her family, and she's subconsciously reenacting a past event that involved violence or betrayal. The 'pranks' are her twisted way of confronting (or reliving) that trauma. Maybe her family has a dark history of 'games' gone wrong. The whole 'St. John Institute for Mental Health' detail seems way too on the nose. It could be a cover for something more sinister, like... she's supposed to be there. Look, I know it's a long shot. But the film's too weird and dark to just be a simple slasher-turned-prank-movie. Let me know what you guys think. Am I reaching? Or is there something genuinely messed up lurking beneath all the 'harmless' April Fool's jokes? Maybe the 'prank' was to see how far people would go before the game got too real?
