While living in Papua New Guinea, I did observe a number of happenings that cannot be explained by science. These weren't anything to do with poltergeists, witches, ghosts etc - but rather come under the heading of what might be termed "Extra-Sensory Perception" (ESP).
In particular, the easy ability of so many of its people to locate missing objects was rather awe-inspiring.
I could go on at length, but one example stood out amongst many others. That happened one Friday afternoon, when I arrived home from carrying out an inspection of the two hydro-electric plants, and discovered that my keys were missing. (I used to carry my key-ring on a Karabiner clip attached to my belt).
The obvious place to look for missing keys is under, around or on top of the car seat - but a thorough search of those places revealed nothing. So I then retraced my steps of where I had been that afternoon, beginning with the lower power station. When that proved unsuccessful, the station staff alerted the upper power station over the VHF Radio Network that I was on my way up to them.
On arrival at the top hydro plant, its security guard went straight for my vehicle (a double cab Toyota Hilux 4WD), opened the rear right hand door, reached behind the rear seat, and produced my keys. (Just in case you are wondering, I was the vehicle's only occupant throughout that afternoon, and had never even sat in the rear seat!) The road between the two hydro stations had a very steep section, which could only be negotiated using Four Wheel Drive, and its surface was extremely rough (rough enough to "shake the fillings loose from your teeth!"). What had happened was that after the clip broke from my belt, the key ring hit the floor and was then shaken, bounced and tumbled both backwards and upwards until it lodged itself behind the rear seat.
The most uncanny thing of all about this was that the security guard said he knew immediately where the key ring was, as soon as he overheard the radio call.
I am open to suggestions, bu this and similar events in PNG have left me seriously wondering about Extra Sensory Perception!
