Response to Orbs
I don't understand what you are trying to prove to yourself. Admittedly, there are a load of idiots out there who'll believe every passing cars headlamps are 'supernatural orbs' but, wise up a bit.
I've seen strange lights in my house recently at night & have not photographed them (yet) but I can't be as skeptical as you about it, I'm afraid (no, I don't mean 'AFRAID'!!!!) My Dad dying recently may be a reason...& then again maybe not - but my mind is open.
