Very interesting dream!
What first came to mind about the entities eyes is, aren’t fly eyes sorta honeycomb looking?
Then I realized that the word Lethalium sounded either Latin or German. I seached online for the word, but didn’t really find anything but a book written in the early 1900’s about Medicine called “Praxis Vulnerum Lethalium” and has to do with Practicing Medicine. I wonder if you were simply being warned about the dangers of modern medicine in general!
Anyways, very cool and thanks so much for sharing!
Love,
Shylo
