They eyelash thing has scared me too when I was a kid. It's amazing what noise your lashes make when your ear is pressed into the surounding matter.
However, here is the proof that what I heard was no eylash, but something very weird in that area. Davey569 has stopped with me within the last few days, and I'm sure he will testify that it is just not possible to sneak up on anyone without considerable noise, and that I am not at all scared by anything and can rationalise noises as I am very knowledgable about nature, animals, and the noises they make.
The date on this might weird Dave out, but he is away doing his army stuff for a few weeks.
I have also slept on battlefields within metres of enemy territory, and done so many covert OPs in NI that I've lost count. I refused to be scared by this stuff, but I cannot get to grips with the weirdness of it all.
