My belief about reality and fantasy

I believe that every place, magical being, god/goddess, curse, legacy and all other things mentioned in fantasy books are actually real and reside somewhere in this universe or on this planet (like the gods/goddesses of greek mythology who in the book series Percy Jackson & The Olympians live on top of the Empire State building or the place behind the wall in the book Stardust). I believe that heaven, hell, ghosts and rebirth into another body exists and everyone will move on after they're death according to their belief or what's closest to their heart. Cause If there would only be heaven then wouldn't heaven be overcrowded and the souls in heaven might grow bored after a certain time.
