Dissociation is also a means of controlling the social and sensory data we’re taking in, ignoring inputs that have become too intense. For example, when there are too many people around, my friend Angel says he goes away into “Angel World” in his head, and everyone around him becomes blurry. He has some relatives that he has never seen the faces of, because he’s only ever met them at big family gatherings where everyone blends into a sea of muddy, vague shapes. When he’s dissociating, he can still go through the motions of eating, bathing, and walking around, but mentally he’s not really there.
