One afternoon while sitting in a Nursing Home visiting with my mother in law, I've noticed something appear on the wall. A fairly large circle with wide "zebra stripes" within the circle. The circle did not move and disappeared after a minute or two. I was not on any medication etc and have not seen anything like it since. Thanks.
Maybe a shadow?
Did it look like this? A bad Omen! A very bad omen, indeed. You will soon be visited by a Herbalife salesman. He will not take "No" for an answer. Buy plenty of toilet paper, while you still can.
Most likely the sun reflecting through a glass or jar or something.
I would not sweat this, I agree that is was most likely a trick of light reflecting off of something. Especially if you have not seen it since the nursing home.
Other people asked questions on various topics, and are still waiting for answer. Would be great if you can take a sec and answer them
