Quote from puinkeyWhat actually is the most common form of a "ghost" ?
*just asking out of curiosity
ehh usually ghosts are the spirit forms that they were when they were when they were living. (i saw my grandma 2 weeks after she died walking and waving at me with a smile.) but others are convinced that its not real. but since you can't "prove" there are ghost at all then nobody knows what it looks like.
