The witches in macbeth, the witches in macbeth, the witches in machbeth.

I always had an image of the witches as being kind of tall with a surrounding gas. I thought it would show Macbeth walking in to a flash of lights and demons throughout the room. I definetly saw some different interpretations of what the witches looked like in the videos. But I think Shakespeare will really be the only one that understands the true image of them. Or maybe he intended them to be that mysterious.
