Your story reminded me of really trippy thing that happened once.

I was talking to a woman in an office-The area was kinda dark and I was standing with my back to a window and she was facing me.

We made eye contact and I noticed that she had this weird pattern in her pupil. I thought, "WOW, this is strange.." and stood there, really freaked out.

Then I remembered she had an ocular lens implanted in her eye and that was what was causing this strange honeycombed pattern that the light reflected.

IT was really bizarre and I know when to question it when I see a twinkle in a woman's eye!

Hope your incident is nothing to worry about.
