Culture shock is a common experience for individuals who travel or move to a new culture or social environment. It often arises from a sense of disorientation, confusion, and stress that results from an expectations-reality mismatch, i.e., the difference between what one expects and what one encounters in a new cultural context. This can lead to feelings of anxiety, self-doubt, and isolation as one tries to navigate and adapt to unfamiliar cultural norms, values, and behaviors.
