Can quantum physics partially explain ghost sightings?

OK, before you think I have gone barking mad or I am some kind of eccentric professor from a 50's sci-fi movie, it isn't as daft as you may think.

If you look up "The Double Slit Experiment" on Youtube, you will see a video being explained by a sort of American cartoon character. Don't let that put you off. The content is fascinating. To briefly explain the double slit theory. When they fired electrons through a single slit at a target board behind they made a single stripe (as would any particle - be it a marble or an electron) but when they fired electrons through two slits they made an interference pattern of many stripes on the target board behind, as if they WEREN'T acting like particles but waves. Baffled by this they put up a device to watch the electrons pass throught the slits and how they behave. As soon as they did this the particles switched from behaving like waves back to behaving like particles. It was almost like the particles knew they were being watched and switched their behaviour. Pretty spooky on it's own, and remember this was a scientific experiment, not a paranormal experiment.

Now if we take a small leap of faith (well a massive one actually) and say that spirits are indeed a form of energy. Could it be that they are simply behaving like the electrons in the Double Slit Experiment, and the simple observance of them makes them automatically act differently and even disappear from sight? - could it be that the simple act of pointing a camera or measuring device at them makes them undetectable or disappear altogether from sight? - makes you think doesn't it?
It was a good friend of mine who told me about the double slit experiment and it has intrigued me ever since. This is of course complete and total speculation on my part, but it is at least a semi-rational explanation isn't it?
