I instinctively try to make the least bald assumption possible. Of course, as we exercise unconstrained imagination, we could imagine a ghost being so mighty it would materialize beautiful LaTeX documents right on our hard drives manipulating magnetic particles on them. Nevertheless, if I forget about the doubt in ghosts existing at all for sake of fun or whatever, the next doubt I have is they can manipulate the matters of material world with ease and precision - even if they could manifest a blow of a wind it would probably be hard for them to manipulate it precisely enough to produce continuous ineligible speech.
