I'm having a hard time understanding you for one thing. So let me try and figure it out.
So it's a red eyeball, light red is it where the irus generally would be or the cornea, and a dark pupil? Then it also has a iron knocker under the eye? Is there any writing? Any detail?
It's probably nothing, we all see things from time to time. I see Ankhs in my dreams, sometimes I see an upside dowb cross with a circle around it. I wouldn't worry to much.
