Anatopia

An Anatopia is a disturbance in space and time that interferes with the person's consciousness, the person is being "teleported" into other worlds and may or may not come back into a normal state of consciousness, it is a symptom of Catathymia and Phrenosis, the person does remember their experiences.

No matter how long the experiences last, in the objective space (real life), it only lasts for less than a second and isn't noticed if the experience does not last eternally.
