Neil Arnold thinks that a lot of monsters, ghosts, UFOs & other strange creatures are from the human psyche. Even SHJ is merely a projected version of the Bogeyman. Neil is interested in the paranormal but remains skeptical about several accounts. Certainly several apparitions can be dismissed as a trick of the light but sometimes it could be tricksters or other dark energy beings. There could be several bands or layers to the universe & the universe could be a component of a Multiverse. Thus, several benevolent beings & malevolent entities might appear from other realms in the cosmos.
Neil like a lot of people, would need to see tangible proof of the UFO enigma. Of course even if you see one it can still be dismissed by others. However, some encounters & data prove to be very compelling. Neil mentioned the zoo of deep tunnels in London's underground & other mysteries. http://www.beastsoflondon.blogspot.com/
