That the spirits of deceased humans are in heaven or hell, not wandering around old farmhouses rattling chains and throwing dishes. That however does not negate the reality of spirits, both good (angels) and evil (demons), both of which are certainly real and do sometimes interact in perceivable ways with human beings.

A ghost is popularly held to be the disembodied spirit or soul of a deceased person. Popularly described as insubstantial and partly transparent, ghosts are reported to haunt particular locations that they were associated with in life or at time of death. A revenant is a deceased person returning from the dead to haunt the living, either as a disembodied ghost or alternatively as an animated (“undead”) corpse.
A related concept is the poltergeist, literally a “rumbling ghost” said to manifest itself by moving and influencing objects. Phantom armies, ghost-animals, ghost airmen, ghost planes, ghost trains and phantom ships have also been reported. Also related is the concept of a fetch, the visible ghost or spirit of a person yet alive, a notion widespread in shamanistic cultures. Necromancy is the purposeful summoning of the spirit of a dead person for the purposes of divination. The word “ghost” may also refer to any spirit or demon.
A poll conducted in 2003 showed that more than half of adults in the United States believe in ghosts and/or demons.
In literature, notable ghosts have appeared in works of Aeschylus in Classical Greece through Shakespeare, Dickens, Oscar Wilde and many others. Cinematic depictions have been diverse, and ranged from Casper the Friendly Ghost to Beetle Juice and Freddy Krueger, in comedy and children’s genres as well as horror.

GHOST – A disembodied spirit. Christianity believes that God may, and sometimes does, permit a departed soul to appear in some visible form to people on earth. Allowing for legend and illusion, there is enough authentic evidence, for example in the lives of the saints, to indicate that such apparitions occur. Their purpose may be to teach, or warn, or request some favor of the living.

I believe you are correct.
To the best of my knowledge the Catholic Church has no official position on ghosts. The doctrine of heaven and hell would seem to negate any reason for ghosts to be the souls of dead people.
However paranormal phenomena seems to exist. These phenomena may come from sources other than the souls of people in heaven, hell, or purgatory. We simply do not know.
The Church is very suspicious of people who claim to talk to ghosts.
With love in Christ.

Not true. Catholics believe that spirits can exist evil and good and they can appear to us.
There is nothing in the Church to the best of my knowledge that says Heaven, Hell and Purgatory are necessarily PLACES but rather states of being.

The devil’s ghost hates the Roman Catholic and make scandals against it.
The good spirit crying for help through the members of the Roman Catholic Church.

If there is a spiritual presence, then its a demon, not a ghost.
