Q: Strange pictures pop up on my camera roll...

I've already seen posts about pictures of trees or something appearing on one's iPod. But this is...different.

Every once in a while. I find photos on my iPod camera roll. (iPod 4) but the disturbing thing is... They're pictures of me. I've had about five of these, but I only have 2 because I deleted others.

This is one of them. I know what is there, its a part of my head, with the curtains of my room closed, and light going through them.

This is a more recent one:

I recognise a few things, the blue plaid is the bottom of my pyjamas, and the striped green/yellow/blue lines are some of my bed sheets. I can't recognise anything else other than this is an angle that cannot have been taken from me...

Another disconcerting thing is that I kept my iPod in a desk drawer the night before this photo... It was hidden.

All the pictures have a few things in common:

-they all seem to be taken during morning, before I get up in the morning

-they are all blurry

-I'm always somewhat in them.

A bit of information before answers:

I NEVER take selfies, so it would be strange if I somehow sleep-selfied.

I'm always aware of my surroundings, I don't think somebody would take a picture of me unknowingly.

I sleep alone

And I don't recall taking any of these pictures.

Is there an explanation? I'm getting kinda worried.

Yours sincerely, Felix
