Analysis. From his first exposure to them, Harry is much more sensitive to the effects of Dementors than anyone else – Harry alone, of the six people present in the train compartment, passes out when the Dementor enters to search it.
A Dementor – a creature within the novel that Rowling utilizes to personify depression – gets onto the train and almost automatically goes to the car that Harry is on. As soon as the dementor enters the cabin, Harry faints and is affected by the dementor.
Well when dementors suck your sole they make you only think of the saddest things. Also when they take your sole they make you very weak and since Harry is now weak and thinking of his parents dieing now he well he just faints. He faints because it is too much for him to take.
Why does Harry get attacked by Dementors on the train?
The dementors attacked Harry Potter on the train because he was a better source of the energy they require than Sirius Black, who they were actually searching for [1]. Additionally, Harry's reaction to the dementors was particularly strong, making him an easier target for them [3].
Because Harry was listening in where he had no business listening in, and Draco had a major grudge against him for being the cause of his dad's imprisonment in Azkaban. He petrified him and threw the Invisibility Cloak over him in hopes that Harry would be halfway back to London before the spell wore off.
He didn't want to make Harry uncomfortable; after all, they live together, eat together, work together and even share ownership of a temperamental cat. Harry just laughs, “I'm in love with you too, you git.” Draco kisses him, putting years worth of pent-up longing into one moment.
Malfoy hated all the attention Harry recieved . Malfoy thought Harry was a dark wizard, he tried to befriend Harry but he refused because of the way Malfoy treated Ron whom he already made friends with. That's why Malfoy hate Harry for turning him down.
Harry describes Umbridge to Sirius Black, saying that she's vile enough to be a Death Eater, despite not being one. Umbridge is also depicted to be a prejudiced person, despising half-breeds and Muggle-born witches and wizards to the point of firing Hagrid due to his half-giant birth status.
With Harry and Hermione despondent after the events in Godric's Hollow and Ron trying desperately to find his way back to them, it was Snape's Patronus – the Silver Doe that was somehow familiar to Harry, perhaps because it recalled his mother's own Patronus – that brought them back together.
The scream he heard was his mother's as she was killed by Voldemort. This was his worst memory and the dementor latched onto it. Harry then fainted. A little later he learns how to fight them off though so he is okay.
Apparently, Umbridge's mother was a Muggle and her brother was a Squib – a source of huge embarrassment for the family. Perhaps their abandonment and retreat back into the Muggle world had such a huge impact on Umbridge that it became the catalyst for her Muggleborn-targeted cruelty later on in life.
When Dementors attacked, they often caused victims to relive their worst memories. Even though Dudley was unable to acknowledge their presence, the creatures were able to manipulate his mind.
Trying to kill Harry is as close to death as Voldemort had ever forgotten, which would have most likely been a very bad experience for him. This theory adds that Harry blacking out after every Dementor attack could have been because it was the piece of Voldemort's soul which was in really bad pain.
Behind the scenes. It is possible that chocolate is used to ward off the effects following meeting a Dementor as it has chemicals inside it that stimulate the release of endorphins, which are chemicals produced by the body to combat stress and pain; often leading to feeling of increased happiness.
A doe. And in his final battle with Lord Voldemort, Harry explained the significance of this to his adversary, and to us: 'Snape's Patronus was a doe,' said Harry, 'the same as my mother's, because he loved her for nearly all of his life, from the time when they were children'.
Notably, Voldemort appeared to be entirely unaware of this split, as he later created a seventh Horcrux in his quest to have six, and continued to target Harry Potter despite him now holding part of Voldemort's own soul.
However, at the very moment of triumph, when Draco had cornered Harry and his comrades, and when it seemed that Harry must be expelled by Umbridge, Harry slipped through his fingers. Worse still, Harry managed to thwart Lucius Malfoy's attempt to kill him, and Draco's father was captured and sent to Azkaban.
He is closely associated with the Order of the Phoenix, and has explicitly denied the anti-Muggle/Muggle-born ideology of the Death Eaters. There is quite literally NO plausible way Hagrid could be or ever have been a Death Eater.
If you have only seen the films, you might be surprised to hear that it wasn't Cho Chang who betrayed Dumbledore's Army to Professor Umbridge – it was Marietta Edgecombe. A friend of Cho's and a fellow Ravenclaw, Marietta (reluctantly) joined the DA.
Draco's belief in the superiority of Pure-Blood status influenced his prejudiced behavior, including calling Hermione a "Mudblood," but he eventually sought redemption by breaking away from the Death Eaters and saving Harry's life.
Throughout the 1996–1997 school year, Draco Malfoy would go to the washroom to find company with Moaning Myrtle, confiding the stress of his mission and fear of failing it.
Lucius disdained the Weasley family for its poverty and so-called blood traitor status; while the Malfoys prized their pure-blood heritage, the Weasleys accepted Muggles and Muggle-borns.
