Anthropologists conducting fieldwork may experience a particular kind of disorientation from the strangeness they discover, something that is often attributable to problems with culture shock. Culture shock is an experience a person may have when one moves to a cultural environment which is different from one's own; it is also the personal disorientation a person may feel when experiencing an unfamiliar way of life due to immigration or a visit to a new country, a move between social environments, or simply transition to another type of life.
