Remember when Jesus said something like “Do you think I’m a ghost!? Do ghost’s have bodies? See the holes in my hands.” (Or something like that).
However, it may be that the spirit is NOT the spirit of the former person (such as the “dad” in my story) - but is perhaps an angel, or demon - using the form of that person.
One of the pastors at our church explained to my wife that the Nephalim USED to have physical bodies on on earth but were destroyed in the flood. Although their spirits are still around. (Something like that anyway).
You know, there is a test to see if the apparition is demonic.
Ask for an embrace; if they embrace you with your hands and theirs around the waist, it’s friendly.
If around the shoulders like a lover, it’s a demon.
I’m iffy about the friendliness of ghosts mainly since, if Heaven is so great, why leave Heaven to come to Earth? In fact, given that Sheol is such a horrific place, it makes sense that a soul doomed would prefer to mingle on Earth, since Earth is as close to Heaven as they’ll get.
Again, demons are smart and it’s just a few simple small tests to be sure.
“Jesus said something like “Do you think I’m a ghost!? Do ghost’s have bodies? See the holes in my hands.””
Exactly; even Jesus let Thomas test his hands to prove Himself that He was truly who He said He was.
I don’t believe in ghosts. We do have angels and demons though.
