When My Brain Shuts Off

I will be fully engaged in a conversation, task, or activity and my will just randomly shut off for a few seconds. What basically is I zone out so much that I not in physical reality and I'm just inside my head. I can't hear anything and it's like I have vision of the real world but I have tunnel vision inside my thoughts. Sometimes I'm just blank but other times I just daydream. I think this might be dissociation or my brain is being over worked and needs a break. I don't know, but some days I'll just feel like I'm not actually fully in reality. I just feel off.


Depersonalisation disorder is characterised by feeling detached from one’s life, thoughts and feelings. People with this type of disorder say they feel distant and emotionally unconnected to themselves, as if they are watching a character in a boring movie. Other typical symptoms include problems with concentration and memory. The person may report feeling ‘spacey’ or out of control. Time may slow down. They may perceive their body to be a different shape or size than usual; in severe cases, they cannot recognise themselves in a mirror.
