If a ghost is clever enough to make itself seen on a TV camera, why is it so stupid as to not make itself and its message clear?

I believe that all communication has a clear objective, and that fidelity of exchange should never obfuscate, open content to misinterpretation, or function as a parlor game. Otherwise, why communicate at all?

If the appearance or message of a ghost is obscure, ignore it. Or tell the ghost to improve its communication skills because you have better things to do. Why even attempt to decode it like the cover of a hard rock band's album? The problem is not yours--it is the ghost's.

Unfortunately, a lot of people are also stupid. They pounce on anything.

Could it be possible that stupid people, after they die, become stupid ghosts?
