As to why others do so, well, there are many reasons: escaping into a mentally created fantasy can perhaps provide folks with a certain level of satisfaction or control that they feel may be missing from their daily lives; it can grant them an opportunity to explore personal interests that they feel they rarely have a chance of doing so; perhaps it can grant them desires or needs that are missing from their daily lives; or it can provide them with an escape from whatever stress or other difficulties that they may be experiencing.
