Everyone has wondered at one point or another in their lives, regardless of their age, whether ghosts exist. The concept of ghosts has been virtually omnipresent since eons, however there are numerous theories supporting their existence and vice versa. Despite several first-hand accounts of ghost-interactions, there is a great chance that they do exist.

There is a good chance that confirmation bias leads many individuals to believe in ghosts, and the beliefs only strengthen over time as you listen attentively to this fictional narrative(movie).
