nightmares! i used to have some horrible ones 
Me too, years ago. Almost always involving me fighting wars almost single handed. Or, hands holding knives coming through my letter box. Or, being shot at. Though the worst of all were those which panned out like horror films - which I never watch. One nightmare had me going round this big, old house, as though I was a would be purchaser, though no way would I have bought that creepy place; there were evil fairy trolls with sharp knives in all the walk in cupboards, just waiting for me. It was alright in the end though, I got my daughter and I out of there. It was all just sexual sublimation, of course.
