We are having a terrible time with or 8 year old dd who has over the last month or so has become terrified of going to sleep by herself. She states this is because she is terrified of having nightmares and is worried there will either be a fire or someone will break into the house, she has had no experience of either of these things. She is also waking up every morning at about 4am and lying on our bed will not go back into her own room. I have no idea how to help her with this and we are all knackered.
