Sound Access to Parallel Realities
A disturbing 1987 experiment conducted by acoustic engineer Dexter Halprren in Milfield, Ohio. Halprren's investigation into sound frequencies allegedly led to the unintended discovery of accessing parallel realities. His experiment resulted in unsettling phenomena, including changes in air density, self-vibrating objects, and an inexplicable sound from within his walls. Neighbors reported seeing still figures and hearing strange whispers emanating from his basement, even in his absence.
