Incoming sceptic rant. Take cover.
Well, that’s truly baffling. A photo of a castle window showing… something… that looks a bit like a face.
Honestly, this “ghost sighting” doesn’t even look much like a person. Sure, that ligth spot looks a bit like a face – an awkward face at that – but then again, our minds have a tendency to see faces everywhere. With that said, this could be anything.
And that brings me to something more important: this is something unidentified. That does not justify jumping to the conclusion that it could be a real-life specimen of the age-old superstitions about dead people “coming back”.
None of the various wild speculations that the concept of the ghost relies on have ever been proven to even be plausible. The existence of ghosts does not deserve the benefit of doubt.
That means the explanation that says this photo depicts a ghost is just as likely as any other randomly speculated explanation one can dream up – and significantly less likely then so many explanations that do not rely on forces that have somehow managed to remain completely unknown to generation upon generation of scientific investigation. It’s on par with an infinite amount of possible explanations in terms of faeries, gnomes, sentient talking plants from the future or flying spaghetti monsters, and inferior to a smaller amount of explanations in terms of deliberate tricksters or a simple play of the light.
