Is what you see real, or is your brain playing tricks on you? Is someone trying to deceive you or make you believe in the impossible? Or is it a technical bug that's caused such a weird snap to be taken? Sometimes, we'll never know!
They're apparently genuine, but the following photos still leave a sliver of doubt... These snaps seem too coincidental to be real, but unless it was us behind the lens, how can we know for sure?
1. When you drop your cell phone just as you're photographing a sunset
