"Oh, I do know Steven King. Horror writer mostly, no?" He doesn't really enjoy horror. He has enough of that in his real life. "Anyway, ghosts mostly cannot be seen by people, only sometimes, if the person is supernatural somehow or the ghost is really upset or really close to them? And they cannot touch things most of the time. Again, unless it's important to them or they're upset. That is how you get-- you get-- poltrygeists, yes?" That's the word in English, he's pretty sure.

He is not quite right, sadly.
