Moving house with children

Have you ever had one of those crazy nightmares where you found yourself in a strange place that was full of people and items you recognised, but thrown together in a peculiar way or weirdly altered by your subconscious?  Or perhaps in your dream you started out in a room that you recognised, but then stepped outside the door and discovered a completely alien environment.

If you have had one of those dreams, I'm sure you'd agree that the effect is horribly unsettling. Yet that's what parents often inflict on their children in real life.  It's called 'moving house'.
