"A Sunken Feeling" is an orchestral piece from the Season 6 soundtrack. It is a variation on the piece that plays at the end of the season premiere's teaser, featuring several more instruments and blending with the main theme.
Jack, on the flash sideways Flight 815, struggles to remember whether he has met his neighbor. The view then shifts out the window and down into the ocean, where the remains of the Island are shown, now submerged beneath the Pacific Ocean. Underwater, the remains of the DHARMA Barracks are visible, and a DHARMA shark is seen swimming near Tawaret's four toed foot.
