Tegan's Dream-State Suppression Earpiece and Hypnosis System

A combined suppression system consisting of two interconnected components: (1) Tegan's Dream-State Suppression Earpiece - a small, curved earpiece clamped into Tegan's ear with rubberized contour conforming to her ear canal, delivering neural interference frequencies to suppress dream-state brainwaves through wires feeding into a handheld hypnosis generator; and (2) The Dream-Suppression Hypnosis Machine - a small console mounted on a bedside table with temporal oscillation gauge controls that projects a faint electromagnetic hum. The machine's cable connects directly to the earpiece. Blue-tinged readouts track suppression of dream-state frequencies that the Mara requires for possession. Designed as a barrier against psychic intrusion, the system physically and psychologically resists invasive mental forces. Its removal causes immediate distress in Tegan. Nyssa and the Doctor are observed adjusting settings during Tegan's vulnerable state, while the Seer deftly assists when removal is needed.
