My most recurring nightmare is of losing my aging father in a crowd, and then being unable to find him. This was something that never happened, although he did try to walk out of a hospital for a cigarette once with no idea of what room he was to go back to. You'd think almost twenty years since my dad passed I'd not still be having that dream. I wonder if the parents of small children have a similar nightmare often? Never had any children so I have no idea about that.
