A few years ago I had a pretty stressful period (short, but unsweet) after one of my parents died, the family was arguing over the estate and work was a major bitch.

The one evening I had to go down to the local supermarket to get some stuff for dinner. It was only a 10 minute drive away. I was feeling fine.

When I got out from the supermarket after making the purchases, I didnt recognise anything and I had no idea of where I was, how to get back to where I lived or even how to start. (this was a trip that I had done 100´s of times).

I started to panic a bit when nothing came to me and forced myself to calm down and ask someone where I was and where a local landmark was. After about 15 minutes, it all came back to me and I was fine.

But it was a complete blackout and I have often wondered what was happening inside my brain.
