Stranger senses

I feel that my life isn't real.

I feel that my life is a big movie playing out and I have no say over it.

Let's I'm in my dad's taxi. In my mind I can see myself sitting next to him, but fast forwarded so we can skip the awkwardness. In my mind, I am simply waiting for the fast forwarding to happen. It is a natural thing.

I see my friend entering the taxi from the back and she is talking and I hear her, responding appropriately to her questions and ramblings but in another part of my mind, time has dulled to nothing.

A friend once told me what I described is a form of hyper awareness. He said it was the most beautiful description of it. He insisted that it wasn't a medical condition, nor is it a psychiatric issue - just awareness.

How do I switch it off?
