My question is inspired by the gospels of Matthew and Luke. Concretely, by Matthew 14:26-27 and Luke 24:36-39:
26 When the disciples saw Him walking on the sea, they were terrified, and said, “It is a ghost!” And they cried out in fear. 27 But immediately Jesus spoke to them, saying, “Take courage, it is I; do not be afraid.”
[Matthew 14:26-27 NASB]
36 Now while they were telling these things, Jesus Himself suddenly stood in their midst and said to them, “Peace be to you.” 37 But they were startled and frightened, and thought that they were looking at a spirit. 38 And He said to them, “Why are you frightened, and why are doubts arising in your hearts? 39 See My hands and My feet, that it is I Myself; touch Me and see, because a spirit does not have flesh and bones as you plainly see that I have.”
[Luke 24:36-39 NASB]
These passages tell us about the worldview of Jesus' disciples. They believed that apparitions of ghosts/spirits were a real phenomenon, to the point that in at least two instances they mistook their own Master for apparitions of this kind. This makes me wonder: why did the disciples have such a worldview in the first place? Was it rooted in actual experience?
Do ghosts exist?
Do disembodied spirits exist?
Are stories of paranormal activity real?
