I would also not call them "dead people" HAhahaha!!
What can you call them? I like to use terms that describe so I might say. "Bodyless people." or peoples spirits.
Note by the way that people do not have to be dead to appear. Also note that we have seven bodies and the one that chooses to go and appear to you could be doing it on its own. Especially people who don't have it all together.
Love the Pun.
People who have not integrated all their personalities tend to have more subconcious wanderings than those who have.
I often hear. "That medium was a charlatan because my brother is not dead. " I
feel charlatans and fake people. I am sure we all do when we listen to our silence. That is normally my first clue and then Charlatans behaviours are often a predictable typical dead giveway.
There are charlatans but I have come across the occasion where a good psychic saw a living person and were ridiculed for it.
