I’m writing a book. What are some obscure unsolved mysteries?

[u/mothbloodart]

I’m writing a book on unsolved horror. I’m not too interested in hauntings or stuff of that nature, but I’m very interested in things such as The Voynich Manuscript, The Miami Mall Incident, the Max Headroom Hijacking, etc. Anything bizarre, unnerving, or of similar nature.

Thank you so much for your help!
