Chewbacca. I have twice bought new prescription sunglasses and packed them in my suitcase to take to Australia. On both occasions they were not in my case when I arrived, and have not been seen since, in either country.
I also bought a Terry Pratchett book called Pyramids, as part of a gift, and put it in the wardrobe where I store gifts until they are needed. That, also, vanished from the face of the earth!
Nothing so weird has happened since, but not knowing how they disappeared is a constant niggle at the back of my mind.
Your 'happenings' are even more spooky, and I can't think of a rational explanation for them. I don't believe in the supernatural, but there are some things that just don't seem to have any other explanation. Maybe there is a ghost sitting somewhere, in a sunny garden, wearing my sunglasses and reading Pyramids! 
Just had to put on a cardigan!
about this. Any ideas GNetters?
