Hi Phil,
I think that they are all photographic anomalies which are therefore 'fake' ghost pics!
I have seen the first one before. It was taken by a man and his wife as they drove past the famous 'haunted' hotel in America. I feel it is just another anomaly of light.
The church lights could be dust or a moth, and the last picture looks like an image developed from the end of the reel of a 35mm camera.
The second one is odd, but I think it may be a thread or strange refraction of light caught at the time the image was taken. Or there was something on the lens like a fine piece of cotton or hair.
Cheers mate.
