Metalapse

Metalapse is a term used in the field of cognitive psychology to describe the phenomenon of experiencing a shift in one's sense of self or identity. This shift can occur suddenly and is often accompanied by a sense of disorientation or confusion. Metalapse is distinct from other forms of identity change, such as those that occur over a longer period of time, as it is typically a rapid and unexpected event.

The term was first coined by psychologist Robert A. Kihlstrom in the 1980s. He defined metalapse as a "rapid, unexpected, and often disorienting shift in one's sense of self or identity." Kihlstrom suggested that metalapse can be triggered by a variety of factors, including stress, trauma, or significant life changes.

Research on metalapse has been limited, but some studies have suggested that it may be associated with certain mental health conditions, such as depression and anxiety. It has also been linked to experiences of near-death, where individuals report a profound shift in their sense of self.

Metalapse is a complex and poorly understood phenomenon. Further research is needed to fully understand its causes, effects, and potential treatments. However, it is clear that metalapse can have significant impacts on an individual's sense of self and well-being.
