There is a phenomenon called "Pareidolia" by which the human brain thinks it recognizes patterns (especially human faces) that aren't actually there. It does look like a grumpy (or maybe apathetic) looking cyclops! Just like this, but only with one eye:
Beyond that, the above element looks like an upper case variant of the Greek letter Theta ( ϴ ), where the central stroke isn't connected to the ring. If it was upside down (the stroke/bar above), it could also double as a numeral in classical Greek specifically the number 9. Keep in mind that the numerals we use today were originally invented in India, and didn't reach Europe until the end of the Middle Ages, via the route of Arabia (which is why we call them "Arab numerals"). Most importantly, the ancient Greeks didn't know the concept of "zero" yet.

Some of it I don't clearly remember but I was in some kind of small church or chapel with no windows. It was really... I don't know how to describe it, kind of warm like the air was thick.
There were some papers over on one of the tables and I saw this symbol. It was an oval with a dot in the middle and a line underneath the whole thing. It was on all of the papers.
Does this symbol mean anything to anybody? it's bugging me.
