I had an interesting conversation yesterday with someone from the mental health trust about some of my stranger mental episodes, the ones where I feel completely separated from myself and my own life. Sometimes it's as though I'm observing the world through a pane of glass. I often feel completely disconnected, have no feelings at all, neither good nor bad, and I can even start to feel as though I'm unreal and my life is unreal. It can be quite distressing at times and it definitely creates a certain amount of distance between me and the people I care about. Anyway, I've now been given a name for these experiences - they come under the broad heading of "dissociation."
Dissociation is a form of psychological defence that has been called "the escape when there is no escape." I'm simplifying here but it's seen as the brain's attempt to protect the person from unpleasant experiences - events that are so traumatic they can't be processed and instead are 'pushed away,' denied and compartmentalised. Used as a buffer against trauma, this protects the person from an unpleasant reality they'd rather not face. Unfortunately, over time, the process can start to take on something of a life of its own and the person can continue to dissociate even during non-traumatic experiences, thus interfering with their ability to be fully present within their own life.
There are many forms of dissociation, ranging from day-to-day experiences that most of us are familiar with, such as making a familiar car journey then not remembering how we got to where we were going, or getting lost in a good book; to full blown identity splits in dissociative identity disorder (the more recent name for what used to be called multiple personality disorder). Clinically- significant dissociation is believed to be an over-zealous defence against stress, but whereas in most people the dissociation is transient and reversible, in some people it has longer-lasting effects.
Dissociation can sometimes be a symptom of an underlying mental health issue such as bipolar disorder, but it can also exist as a standalone issue. Specifically, I experience what's known as depersonalisation and derealisation, as well as a good bit of identity confusion. Go me! Intriguingly, it's linked to migraines - something I get a lot of - and epilepsy too, so it appears there may be a neurological connection.
From my point of view, I'm thankful it's recognised as an actual 'thing' and is not simply a case of my wayward brain acting up. I can see how it's a learned response to stress - in an attempt to protect me from psychic difficulty, my brain holds things at arms length to the extent I feel separated and remote from my own life and even start to question what's real. I'm comforted by the knowledge that it's an exaggerated version of what most people experience. Personally I don't see it in terms of illness; I see it more as an adaptation that was once useful but has now become unhelpful.
I'm intrigued about the extent to which dissociation might be related to having a good imagination because it's common for children to dip in and out of "real life" and retreat to what's inside their heads. And not just children, we all indulge in a little daydreaming here and there. Maybe some of us are a little more reluctant than others to return to the real world? It obviously serves a purpose otherwise it wouldn't stick around but I'm finding it troubling and distracting so I'm hoping I can tackle it (along with a host of other stuff) in therapy.
