Sister's Ectoplasm Ghost Picture

Is this fantastic ghost picture of ectoplasm, actually the spirit of Charlotte Holley's sister who is with them in this motor home? Charlotte and her husband reside in Greenpond, Alabama:

"I had sent you a picture, and you put it up in June of our motor home ghost. My husband just got some pictures back he had taken in the motor home, and here is another one (ghost picture). This has happened since my sister died unexpectedly...the last place we saw her was in this motor home.
