Sensory processing issues fall under two categories - hypersensitivity and hyposensitivity. Hypersensitivity causes sensory overload. Imagine experiencing everything much more intensely than you do: imagine the clothes rubbing against your skin feeling like your skin is being scraped by sandpaper, imagine people chatting with each other sounding like they are shouting through loudspeakers, imagine the lights in the room feeling like floodlights blinding your eyes. It would be torture. In fact, such methods ARE used as means of torture around the world.
