8. Princess Alexandra believed that if she fell, a glass piano inside her would shatter
When she reached her 20s, Princess Alexandra became fixated on the idea that, as a child, she had swallowed a grand piano made entirely of glass. However much her father the King or his physicians tried to persuade her otherwise, she was convinced that this glass piano remained inside her and was terrified that it could shatter at any moment. To stay safe, Alexandra became something of a recluse, devoting herself to her literary endeavors. She died at the age of 49 having never overcome her unique glass delusion.
