How common is depersonalization disorder?

Transient depersonalization/derealization is quite common. This situation occurs when you experience depersonalization symptoms briefly. You have a fleeting feeling of being detached from yourself or the environment. You may feel like you’re watching yourself in a movie. Experts estimate it occurs in about half of the population.

It occurs in less than 2% of the population. It’s rare for depersonalization/derealization to need treatment.
