 In fact, the technology used in the episode to induce Mulder's flashbacks was based on various New Age equipment, including a "brain stimulator".The cottage used in the episode was actually a farmhouse located in South Surrey, near where the previous episodes "Home" and "Tunguska" had been filmed.The show's art department rented and refurbished the house, took photographs of the building, then returned it to its original state for the actual filming.
