My 8 year old daughter had a horrible dream a few months ago, which really upset her. Now she is hearing 'voices' from the dream in her head during the day - they don't speak to her, she says it's just the screaming and scary laughing she heard in the dream. She says she only hears it when she's on her own and quiet, not at school or when she's occupied. When she comes over and says 'the voices in my head are back' and is clearly upset, it really worries me. Otherwise she's a very bright and happy child. Will this just go away or should I take her to see someone?
