Does anyone know why some people get a twitchy eye lid when they are tired?

I sometimes find my eyelid can twitch rapidly when I am tired (and it also sometimes happens when I'm stressed).

I know it is possibly not a very scientific question, but does anyone know why this happens? Someone asked me and I realised that I don't actually know.
