My DD had the EXACT same fears, at about the same age!

She grew out of those anxieties, FWIW, but she does have a diagnosed anxiety disorder and counseling has helped a lot with that. She is much more receptive than DS to counseling interventions--she actually wanted to go, probably because she likes to talk and always feels like nobody listens to her.

She gets spooked very easily and I have been able to use this as leverage in terms of what movies she watches, etc. She wants to be "scared" but she takes forever to detox, even from silly Girl Scout ghost stories.

I also have the workbook KJP references, and it's a good psycho-
educational tool.
