Hi, Welcome to the forum.
Straight to an interesting question. Any background?
Ghosts, spirits, etc etc are in the realms that we know very little about. Generally, we can't see it, nor feel it, or hear it.
I believe they are all manifestation of the jinns. Allah has said He created them. .and mankind. . .and angels.
I have had experience with them. And it's a story not very believable. I just pray (dua) to Allah to keep our paths separate, that the jinn does not appear in my realm.
Never really wanted to get it 'exorcised'. I don't understand their realm, I don't believe anyone can truly understand it. Reciting the Quran might do the trick as we are all Allah's creatures, and the Quran are His words.
Ayatul kursi will be a good start.
Have a great stay
