Mack describes a case in which an experiencer feels a presence at the end of the bed. The sensation precedes visual perception, creating a liminal state between paralysis and awakening. The emotional tone resembles the onset of a vivid nightmare.
When the experiencer finally sees the figure, it appears distorted and alien, intensifying the terror. The scene blends environmental realism with the symbolic compression of dream space.
Mack emphasizes that such bedside episodes mark the threshold where dreamlike states and waking perception intersect, shaping many reported encounters.
