“To him who is in fear everything rustles.”– Sophocles (ancient greek poet)
A blank expression is a facial expression characterized by neutral positioning of the facial features, implying a lack of strong emotion. It may be caused by a lack of emotion, depression, boredom or slight confusion, such as when someone refers to something which the listener does not understand.
The thousand-yard stare or two-thousand-yard stare is a phrase coined to describe the limp, blank, unfocused gaze of a battle-weary soldier, but the symptom it describes may also be found among victims of other types of trauma. A characteristic of shell shock, the despondent stare reflects dissociation from trauma. The thousand-yard stare is thus often seen in cases of incipient post-traumatic stress disorder.
