Is prolonged solitary confinement considered torture? How about if it's in a sensory deprivation tank? Then add paralytics. Now contemplate consciousness with no sensory input at all (not even your own heartbeat or normal bodily sensations when you move, etc.) leaving only whatever phantom sensation the traumatized nerves generate, like amputees' phantom limbs and phantom pain, but for your only sensation. On an individual basis this may be the most terrifying thing I could ever imagine.
