As I've started lucid dreaming, there is one flaw that always seems to follow me. I can't help it, at some point I will close my eyes even if only for a brief second (like a blink) and it will wake me up.

Does anyone know any methods that are good for combating this problem? Stability is good... Focus is fairly well... Able to control the dream...
But suddenly *blink* and BAM, its over. Luckily I can normally chain back into it but it is still very annoying --;

So again, methods or defence against blinking/closing eyes anyone?
