pixi, many children go through similar thing, seeing people in their homes. some say its because we are all born to see such things, but that society tells us its wrong and dismisses the idea.
Very interesting story though
I had a friend whose young child was often laughing and playing in the middle of night. The mother thought that it was her deceased brother paying the child a visit, she didnt want to make him leave but asked nicely that he stop waking the child each night at it wasnt good for the child or her own sanity lol. Anyway the waking stopped immediately.
sometimes i think that even if it is a load of rubbish that people need reassurance, if its in their mind and you can calm them they perhaps the instances stop, thats what flyboy needs to do, help his wife feel comfortable in her home
