A long time ago, I had a dream about finding a book of science experiments and mathematical formulas.
Included among these experiments was a very equation-heavy method for receiving messages from another world- a world that the book referred to as “Nil Admirari- The dark star”.
the so called dark star was depicted as looking something like this- a stylized and abstracted representation of some kind of citadel floating in space. Not really a “star” in the strictest sense of the word, but the book looked really old too
Following the experiment’s steps to the letter resulted in receiving horrifying signals that sounded a lot like this
