Its an odd topic. You have some say yes and some say no. This question is a personality test. People who say no cant explain all ghost experiences and people who say yes are also stating they believe in supernatural mystic forces witch sounds crazy. Its an opinion nobody can be right
Yes, I do. I have had an experience that in The Bird Cage Theater in Tombstone, Arizona. While on a tour of the place, on the floor above us (in an off-limits storage room) we hear the sound of like a ball or marble drop and bounce until it rolls. The guide said it was a spirit and I saw the exact same thing happen on TV in an episode of Ghost Hunters and Ghost Adventures at the Theater. My parents have also had a paranormal experience. In my house there was a laundry closet with clothes hangars hanging on it. During the middle of the night, they both awoke to the sound of the hangars moving (which sounded just as someone had brushed past the hangars). The next morning they found out that my Great Grandmother had passed away that night. To this day (this event happened around a decade ago) my parents believe it was my Great Grandmother coming to say goodbye.
The Bible refers to the invisible world as the real reality. We call the invisible people ghosts but the Bible tells us that there are good ones and there are evil ones and they really aren't ghosts as in dead peoples spirits. They are the angels good and bad who battle for our eternity
