It happened the first time, last night. I was on my front porch, and saw a flashing blue light out of the corner of my eye. When I looked towards the spot, the light stopped. I looked a little to the right and could see it again. It was like a shadow of a light blinking on a garage. I searched all over and couldn't find a source.
It happened again tonight. I can see it if I'm not looking directly at it, but when I look right at it- it is gone... It's very frustrating. It only happens at that one specific place. Is this a trick of my eyes? Is it something I should be worried about?
