help? (spoilers, with any luck)

SPOILERS AHEAD

I'll give you what I was able to glean. It's about a little boy named Lucas (Which is derived from the Latin word for light) who is slowly going blind and is going to have major surgery which could restore his sight but brings the risk of making him blind. He lives in a fantasy world of his own and spends his days wandering all over the neighbhorhood spying on people with a spyglass or just by peeping in their windows. The film is about light vs. dark, seeing vs. not seeing, etc. At times it is not clear whether we are watching Lucas's fantasy or reality. It is also not clear how many of the women he sees in his daily walks around the neighborhood are actually blind or if it's just his fantasy. For example, he frequently pictures that his mother and half-sister are blind, which we can see later they are not.

The boy believes that a razor-wielding stalker is slashing to death blind women in the neighborhood. Creepily, at each of these razor-murders the boy just happens to be an eyewitness, though he never tells anyone about them. His father, a policeman, visits the local home for the blind and warns the women to be much more careful. Ultimately (I think) we realize none of this actually happened and the murders were only in Lucas's imagination.

Lucas also seems to have a somewhat incestuous fixation on his half sister and is deeply jealous of her fiance. He wanders out of his bed at night and imagines he spies his sister posing for her husband, a photographer, in a pin-up pose in nothing but knickers and a white cowboy hat. In his "vision" his sister is blind and her fiance walks up to her with a razor and runs it over her body, gently at first and then with enough pressure to cut lines in her thigh. Just as he is moving to slit her throat, the boy imagines himself running up and stabbing the fiance in the eye with a knitting needle to save his sister. Later we see the fiance is perfectly fine and his sister is not in fact blind.

In his lonely rambles, Lucas frequents the graveyard across the street from his house, hides in a mausoleum and romps with a golden retriever. Later Lucas is in the front room of his house and we see the dog eagerly trying to come in the partly open window. One expects Lucas to get up and open the window a little wider to let him in. But instead he imagines that the dog is mad, growling and frothing at the mouth. Suddenly, the mad dog crashes through the window and as with the fiance, Lucas stabs it in the eye with the knitting needle, throwing the dog back out to the pavement below. We are supposed to believe this was also a fantasy, and it still wasn't clear to me whether it was or not. There are scenes where the dog's owner finds the body and takes him sadly to the trunk of his car. The father pulls up and sees this and comments that the dog looks like it was stabbed through the eye.

Ominously, the boy starts carrying a knitting needle everywhere he goes.

Lucas's half-sister gets married and he is not happy about this, feeling left out and neglected. His glasses are knocked to the floor and trampled (probably only in is fantasy.) At the wedding reception, the boy's mother goes into labor. Later they bring the baby home and when the baby is alone in the front room, he takes the baby and runs out to the cemetary in his pajamas. His father puts the clues together and realizes that not only has Lucas taken the baby, but that he is the one who stabbed the dog. He assumes Lucas is going to kill the baby. They all run after him and he hides in his favorite mausoleum with the baby.

Next thing you know he is waking up in hospital with bandages over his eyes and his family are all gathered round him. He asks if his sister is okay and they say yes. He tells them he was just taking his sister to see his "special place" and wasn't going to harm her. He asks them if he killed the dog and they don't answer directly. The end. (I'm sure someone else can fill in more.)
