Who or What are the "Jinns" as is known in Islamic concepts or the "Spirits" as is known in other Religions? They are known to convey true but mostly false information to humans and sometimes even known to manipulate Matter or Events.

A spirit is an old concept that often refers to a ghost. But different countries have different definitions for the word spirit. In some countries, it refers to the "soul". The soul can be another word for our DNA + our memories.

As to Jinns, all we can say is that any story that comes from ancient times often has a true origin but with time it has been distorted by going from mouth to mouth - so much that it probably bears no resemblance to the original true story.
