Some people believe in reincarnation, some in parallel worlds, some in ESP! Some think they have been through it all before! Whatever the reason, it seems to be fairly common for people to have at least one experience of being sure they know someone, when they don’t. Maybe it’s just pure imagination!

　　In Western countries, people are usually not shy about walking up to a pure stranger who seems familiar. They consider there is no harm done if someone they feel they may have met before turns out to be, indeed, a complete stranger.
