When the sound of a bell rings in the haunted house you are at, it could be the voice of a ghost.
But when a ghost emerges from the shadows and haunts you, the real answer is a little more complicated.
According to a study published by the journal Psychological Science in 2015, people who believe ghosts are real tend to believe that their hauntings are caused by supernatural forces, which could be a product of the paranormal.
The study was conducted in Germany, Canada, Japan, and the United Kingdom, and it found that 70 percent of participants believed ghosts were real.
According a survey by the Society for Personality and Social Psychology, ghost sightings can be a sign of psychological distress.
Some people may also believe that ghosts are physically present, or that their presence is somehow linked to otherworldly events, such as death or illness.
So what does it mean to be haunted?
When you think of ghostly experiences, you probably think of the famous and terrifying events in The Exorcist, the haunted houses in Halloween movies, and haunted houses on the Internet.
The answer is not as simple as it sounds.
According the National Library of Medicine, the vast majority of people who experience a ghostly experience are actually experiencing a normal event.
For instance, the majority of the people surveyed did not experience any symptoms or physical symptoms, such in particular hearing a ghost, or being unable to walk or talk.
However, many of these people may have been subjected to traumatic experiences that have affected their ability to feel and react to things that would normally cause them to experience a phantom pain.
These people may experience a fear of being attacked by the spirit, or may have experienced intense anxiety and panic attacks.
Accordingly, these individuals are not likely to have a strong connection to the physical world, and therefore, are less likely to be experiencing a ghost in their own home.
People who experience an invisible ghost are also more likely to experience symptoms of panic and a lack of concentration.
These symptoms can be similar to those seen in patients who experience symptoms related to psychosis.
According more recent research, however, these people are more likely than others to experience hallucinations, and may be experiencing the ghost of a person who has passed away or who has committed suicide.
These symptoms can include seeing people who have died in the past, or seeing people dressed in a strange way, or even seeing objects that resemble corpses.
A study by the University of California, Berkeley, published in the Journal of Affective Disorders in 2017 also suggests that people who experienced ghostly events in the real world have a higher risk of developing PTSD than those who did not.
This means that if you are a regular haunter, you are more at risk of experiencing these symptoms than those you did not see in the ghostly event.
However it should be noted that the study was based on a small sample size, so the results may not be generalizable to the general population.
In the meantime, if you do experience any of the symptoms listed above, it’s important to check out your local haunted house to make sure it’s safe.
