Today I woke up and found 2 new pictures on my camera roll. Here's the thing: they appear to have been saved onto my phone whilst I was asleep in another room (I live alone).
I have never seen these pictures before (1 was a street fashion photo of some random lady, and another was a picture of a cowboy hat), have checked and double-checked my Whatsapp history for anything someone might've sent me, and I've got AirDrop switched off.
Where could they have come from? Am I having visits from Casper the friendly ghost? Has Peeves the poltergeist found a way into my house?
