One theory suggests that whenever we think there is a threat, our body reduces blood flow to areas in the front of our brain (the thinking, analytical, rational part) and 'turns on' areas in our back brain (the automatic, instinctive part).
Using our back brain to freeze or flop helps protect us from trauma that we can't prevent or run away from. But reducing the blood flow to the front brain can make it more difficult to process what happens and may mean we experience dissociative symptoms.
The front brain includes areas which help us:
- understand where we are in time and space
- use language and speech
- feel connected to our body
- store memories
- make sense of information coming through our senses
You might separate different parts of an experience so you do not have to deal with it all together. Different parts of the experience (such as actions, memories, feelings, thoughts, sensations and perceptions) may not be 'joined up'.
I would disconnect myself from being in the room where the abuse was happening. I almost felt like I was watching it happen to me but I wasn’t feeling it or wasn’t part of it. It became something that happened automatically.
For example, you might store an experience in a way you can't access day to day (this is usually called amnesia). Or you might remember what happened but don't feel the emotions or sensations that were part of it (this is usually called derealisation).
If you experience dissociative identity disorder (DID), you might feel as if different memories, sensations or beliefs happened to different people (usually called identity states) inside you.
This can help you cope if the things that happened would be too much for you to deal with all together as a child - but may prevent you from developing one clear identity as you grow up.
What makes dissociative disorders more likely?
Not everyone who experiences trauma will have a dissociative disorder but many experts agree that these things make it more likely:
- abuse begins at an early age (the younger you are the harder you will find it to cope with traumatic experiences without dissociation)
- abuse is severe and repeated over a long period - or by many people
- abuse is painful and makes you scared
- there is no adult who you have a good relationship with and is able to provide comfort and help you process and deal with the trauma
- the abuse is done by someone you feel attached to
- the abuser tells you that things didn't happen or that you were dreaming
- things are different at different times - for example things seem normal during the day but at night you are abused.
