Excellent account. I love this... something about it being about film photography (as opposed to digital photography) makes it so much more interesting in my mind. (I don't think I could bring myself to photograph mirrors though... they creep me out at the best of times).
One thought that occurred to me... (if I put on my sceptical beret and squint a bit)... when the photographs re-appeared after going missing, could the two that you originally saw the gnome(s) in, have still been there, but whatever it was that you thought you saw, no longer manifested itself that way?
To rephrase:
You originally saw the gnome(s) in two photos. Said photos go missing, then reappear, so there is a period of time (several days?) in which the photographs were not there to be looked at, so the details of what was depicted would, therefore, 'fade' somewhat in your memory.
Then, when the photographs reappeared, you could no longer see the gnomes in any of them. But, would it be possible that all the photos
were in fact there, but your mind no longer saw gnome anomalies in them?
It's a stretch, I know, and hopefully what I'm saying makes sense. Was a count done of the number of photos, such that you knew later that there were two less? Etc.
Also
@Eyespy, again an interesting encounter.
My gnome story is much less interesting (in terms of details) but I'll throw it in here anyway: my mum once told me that, as a little girl, she'd seen a gnome on the stairs of her house.
I've yet to find (hopefully someone on here can prove me wrong?
) any other accounts of gnomes
inside houses rather than outside..
