I've never read "Finding Amelia", but I have read a little bit of "Amelia Earhart's Shoes". I'm not really creeped out by it, but it is sad to think that this may have been her fate. Also, within the recent documentary that showed on Discovery, the crab part was kind of eerie. Those crabs are something (especially the Coconut ones)!
If you don't mind me asking, what kind of nightmares do you have? (Odd question, I know)
