What causes depersonalization?

Depersonalization is often caused by a range of factors, including stress, trauma, anxiety, and certain mental health disorders such as depersonalization-derealization disorder. It can also occur as a response to overwhelming situations or prolonged emotional distress, serving as a coping mechanism to detach from uncomfortable feelings or experiences. Additionally, substance use, particularly hallucinogens or alcohol, can trigger episodes of depersonalization. In some cases, it may arise without any identifiable cause.
