Lots of people daydream themselves away from a bad situation, imagine themselves elsewhere, or pretend that they are someone they are not. They imagine a new reality. That’s very normal, and even healthy. Dissociative disorders, however, are not voluntary, and they aren’t even “imaginative.” The brain itself creates a new reality, that, although not real, for the individual is indistinguishable from reality.
There are various levels of dissociative disorders, occurring in 2% of people, without regard to gender, age, ethnicity, or status. The most common symptom is memory loss, which is generally called dissociative amnesia. This is when you forget large and important events and parts of your own personal timeline. This can last minutes, hours, and in more rare cases days, weeks, or even years. This isn’t the “clunk on the head” we see in movies. It is a synaptic event, brought on as a self-defense mechanism.
In some cases, important parts of identity go missing, such as name, address, or personal history. This can sometimes turn into a related disorder, Dissociative Identity Disorder (DID), which used to be called “multiple personality syndrome.” The brain creates a whole new reality, a new personality, replete with nuanced behavior and a whole history. In shorter bursts, this is known as a dissociative fugue state, where days or weeks can be spent as someone else, going to a new town, wandering off, before coming back to reality. The victim often has no memory of what happened.
Another variant is what is known as depersonalization disorder, which the latest DSM now groups under dissociative disorders. This can impact, at one time or the other, nearly 50% of the adult population. This is when you feel completely disconnected from your body and your thoughts, as if you are viewing them through a glass, darkly. While most instances are very brief, there can be prolonged episodes. This is connected with “derealization,” or the feeling that whatever is happening is actually just a dream, that it isn’t real.
It is easy to see why these are so dangerous. A loss of identity, a feeling that you are not yourself, can lead to depression, anxiety, and inability to socialize, a distancing from family and friends, and even self-harm and suicide. When we are no longer ourselves, who are we? And why did we leave?
