Like now when DH is on night shift and I'm on my own.
Sometimes DH is out all night at work (on call cover) and DS stays out/crashes at mates (or whatever he does!!). I am a big wimp.
I go to bed, can't sleep cos I think I hear noises, get up and "investigate" noises (which turn out to be fridge, house cooling down, central heating boiler, you name it) then lie awake thinking of scary movies.
When I eventually drop off, some random little noise will then wake me and my heart will be in my mouth and I'll be scared witless!
It's not even as if we live in the middle of nowhere - we live in a nice street with good neighbours in a small town.
I even leave the hall light on!!
