The brain has a strategy to shut itself off from the body and the surroundings.
This is called dissociation. In normal life, dissociation allows us to ‘forget’ we have a body. This is helpful when we need to focus on other things.
However, when dissociation occurs too often or in extreme forms, it can cause various strange experiences.
Some of these experiences are confusing. During dissociation the brain enters a protective trance. This means thoughts, attention and memory can become foggy.
Dissociation can make someone feel they have lost control of the body. Functional seizures are an extreme form of dissociation.
Dissociative symptoms are reversible, and do not cause the brain damage. However, if the process is not interrupted, dissociative symptoms can begin to affect more and more areas of life.
