Why ghost hunt at night?

I suppose people hunt ghosts at night for the spooky atmosphere, but I personally don't believe it is necessary. I think we'd be more apt to see an apparition in daylight. Example: Sprinkle some dust in the dark. You won't see it. Sprinkle the dust and then take a flash photo....voila.... you will see the dust in the photo. It is the same concept of seeing dust particles in a sun beam.

I suppose having fewer distractions helps at night, too.

Does anyone else have a night time...
