Feeling out of place in one's own environment can be a disconcerting experience. Synonyms for the sense of being alien include feeling unfamiliar, foreign, estranged, or disconnected. Such feelings may arise from social, cultural, or environmental differences, leaving one feeling marginalised or like an outsider. A sense of not belonging or fitting in can cause an individual to feel a loss of identity or a sense of displacement. Other synonyms may include feeling isolated, detached, or estranged. These sensations can be described as feeling like an outsider or a stranger, with a lack of connection to the people or places surrounding them.
