Thinking too much
When I was a child it occurred to me that breathing happened without having to think about it. As I pondered this I tried slowing my breathing, holding my breath in, holding my breath out, until I got bored. This was when I realised I hadn't automatically start breathing again; without conscious thought nothing was happening. Panic set in but thankfully something shiny must have distracted me, because all these years later my autonomic nervous system is doing just fine... *breathe*

On a similar theme, during the antepenultimate exam of my finals I forgot how to spell "of"... ove? ov? I had to rephrase several sentences before it came back to me.

Actually I've fogotton how to spell 'of' a number of times.
Fortunatly for me I have a number of well known learning difficulties and nobody takes the piss out some one like me unless its over the internet/far away. 'Every' is a killer too.
