Why Do Ghosts Wear Clothes?

One of the most glaring flaws in the argument in favor of the existence of spirits, ghosts, etc, is that in the majority of sightings of full body apparition-type ghosts, the ghosts are wearing clothes. If ghosts are indeed the energy of soul of departed humans, why wouldn’t they just be naked? About.com’s Stephen Wagner posed this question to a few paranormal researcher, and got some pretty good, if somewhat vague, answers:

This could be a totally unconscious effect of the energy on the living person, or it could be a manipulation on the part of the spirit itself, perhaps causing the person to see what it wants them to. To understand this, I suggest that you close your eyes for a moment and then visualize yourself in your mind. How do you appear to yourself? Most likely, you were wearing clothing in your imagination. With the idea that a ghost appears looking in the same way that he sees himself, this might explain why so many ghosts that are seen are not only wearing clothing

Hmmm. And if you’re wondering, the picture above is apparently the ghost of Jim Morrison, taken at his grave in the Pere Lachaise Cemetery in Paris.
