In the Bible, in the book of Matthew 14:22-33, the disciples of Jesus became terrified when they saw Jesus walking on the sea because they thought He was a ghost. According to the passage, the disciples were in a boat in the middle of the sea when a great storm arose. They saw Jesus walking on the water towards them and they were frightened, thinking that it was a ghost. It was only when Jesus spoke to them and identified himself that they recognized him and their fear was eased.
