Twin Peaks, Part One

I am watching season one of some classic television and formulating theories to explain the series of events I have been observing – events which are most accurately described as “trippy”:

Theory 1: Laura Palmer was killed by the townspeople to appease the mysterious, eldritch evil that lives in the woods.

Theory 2: Twin Peaks is actually a society completely composed of lunatics. Dale Cooper is not an FBI agent but a transfer from a different asylum, suffering from delusions that he is an FBI agent. Sort of like Shutter Island, I guess. This would explain both his prophetic dreams and obsession with trees.

Theory 3: There are drugs in the water. Lots of drugs.
