Wizeman the Wicked is a Visitor.In the games, Visitors are able to create Nightopia through their personality, memories, hopes, goals, and interests. It makes sense the the realm of Nightmare is Wizeman's Nightopia, a la Nightmare Fuel Station Attendant. Wizeman created not only a Nightopia, but an entirely different plane in the entire Night Dimension. And he can't wake up. This is because he came without the Ideya of Courage, and has yet to find his own Ideya of Courage. After all, he sends all of his creations and dreamed-up people to get things for him, and you only need to hit him, what, three times in the game? Because of that, he has stayed locked in the Night Dimension for years and years, perhaps even defying the laws of physics and aging and being Really 700 Years Old (I read somewhere that sleep slows the aging process by a significant amount, though that might be debatable). He's been stealing Ideya from other Visitors as compensation for his lack of a Red Courage Ideya, yet ironically, the Red Ideya is the only Ideya he cannot steal, nor keep. So he goes on, creating more and more Nightmarens and becoming the God of Nightmare. For years he has been trying to get a Red Ideya, but has failed so often — so very, very often — that over time he has completely forgotten what he had initially set out for. He loses himself, going crazy to try and get at his Red Ideya, that he leaves his waken life completely, even forgetting that he is a Visitor. This causes problems for his 'Real Life' body, which is still asleep. While the Wizeman of the Night Dimension goes on a reign of terror and malice, in a desperate attempt to finally get his blasted Ideya, the Wizeman of the Real World is still a child, doodling designs for Nightmaren and the faces of other Visitors, but only as a subconscious reflex. In fact, Wizeman has become convinced that getting a Red Ideya will wake him, forgetting that it is of his own free will that he awakens. Whatever little boy Wizeman may have once been has been lost, leaving behind a broken child in the Real World and a heartless overlord in the Night Dimension.
Nights survived Wizeman's destruction/defeat/death/indeterminant-hibernation-dreamless-sleep, as did a couple other Nightmarens, due to having part of an Ideya.
Helen's mother went to Nightopia when she was younger.At the end of Journey of Dreams, when Helen plays NiGHTS's song, she nods and has a nostalgic smile on her face. When she was younger, she managed to get through the Dream Gate without losing her Ideya, and met NiGHTS, who helped her overcome her fears the same way s/he helped the protagonists. That's precisely why she has such a look on her face: not only is she proud of her daughter, but she recognizes the song and has instantly figured out what happened.
Everything in the NiGHTS series is based on true events.The creator of NiGHTS was once quoted as his inspiration for NiGHTS coming to him in a dream. The series is, of course, about children going into their dreams and conquering their fears and nightmares. Notice how the goals for each human character outside the dream world are completely realistic goals for children to have; boy wants to defeat rival basketball team, girl wants to overcome stage fright to audition for a singing role, girl wants to balance time with mother and time with friends, boy wants his dad around more in order to boost his self-confidence. Nothing fantastic, nothing magical. Just normal kids who all happen to have access to a unified dream dimension where a certain jester-like humanoid creature lives. If these kids can go there... why can't anyone? Anyone including, say, a grown man who works for a videogame designing company? The meat of my theory is this: NiGHTS met the game's creator in a dream. They became close friends within the dreamscape, and NiGHTS begins to tell the man stories of other dreamers s/he has met. The man, after listening to these stories, decides basing a new game off these stories is easier than being original, and so begins creation and production of Nights Into Dreams. Sadly, NiGHTS' visits with him soon become rarer until s/he stops appearing altogether... until eleven years have passed, when NiGHTS finally returns with new stories to tell. To add slight credence to my theory, listen to this: according to the 2000 US census, there are 29 people in the US named Elliot Edwards, the same name as the male protagonist in the first game. Granted, it also says there is only one (or fewer) person in the US named Claris Sinclair, and the data given for Helen and Will can be thrown out the window as they clearly live in England and not in the US. Still...it makes you wonder.
Journey of Dreams is actually a prequel to NiD.
NiGHTS has two separate personalities, one male and one female.NiGHTS is androgynous by Word of God, yes? This is because xe’s both male and female. The Visitor meets the personality that he or she would feel more comfortable with. This is evident because NiGHTS acts very differently in each dream in Journey of Dreams, and also because either NiGHTS doesn’t seem to know about the other Visitor’s existence until both children rescue hir in the clock tower. By that point, NiGHTS’s personalities had again merged into one.
Nightmarens' entire bodies are invisible except for their heads.NiGHTS doesn't seem to have wrists or a neck, and just look at Jackle.
The jewels Wizeman wears are stolen Ideya
Awakers do not spawn in the Black Sea.This is why you can easily become real-world comatose if you fall in the thing without something to rescue you at the last second. Nothing will drag you up. Night Overs still occur during Bellbridge and Twin Seeds because the Ideya of Courage is willing to substitute and drag you out if you fail.
