In human sexuality,<unk>  also known as rape<unk>  involuntary<unk>  fright (or faint), or tonic immobility, is a natural bodily survival reaction which can be automatically activated by the brain of a person who feels threatened by sexual violence. During this<unk>  one cannot move and cannot say anything, until one feels safe enough again. This survival reaction is a reflex; it automatically occurs without one's conscious choice, and one cannot stop it happening.<unk> is a survival reaction which the brain applies to the body whenever all other options to avoid sexual violence (prevent, freeze (hypervigilance), flight, fight, compromise) have been exhausted. In modern science, increasingly more is understood about when, how, and why<unk> occurs. However, public awareness about<unk> is still limited, which has negative consequences for the prevention, punishment and processing of sexual violence.<unk> is sometimes also called freezing, although scholars prefer avoiding this word usage to prevent confusion with the 'freeze' (hypervigilance) response that usually precedes it (see below).
