What were the Dementors doing to Harry and what exactly is the "Dementor's Kiss"? [duplicate]

If Dementors are controlled by the ministery and looking for prisoners, why did they do that to Harry in the train in Harry Potter and The Prisoner of Azkaban? Is that their expedient effect? (When they accept Dementors to search the students train it means it shouldn’t be harmful or fatal! Wasn’t it?)

Was the thing they did to Harry the Dementor's kiss or is it just the thing they did to Sirius Black? When do they use the Dementor's kiss?

Is their effect permanent or is it just for the time they are around?

(I read Pottermore but I didn't get my answers. This link can be useful but because English is not my language it was hard for me to read it.)

Best Answer

During Prisoner of Azkaban, the Dementors were supposed to guard Hogwarts Grounds against Sirius Black. Evidently, they went to the trouble of checking the train which was occupied by Harry, and they thought he was Sirius Black.

Enough time and Dementors would make you mentally damaged and/or take away your soul via the Kiss. However, Remus Lupin was there to prevent from the Dementor doing further harm to Harry. As long as they are around, it will turn very cold and make the surroundings feel very horrid.

What was the Dementor doing to Harry?

Why did the Dementors affect Harry so much?

Tumblr user swan2swan was the first to help shape the theory, by explaining why the dementors were so bizarrely fascinated by Harry in the first place \u2014 it wasn't because he was the one they were ordered to protect, but rather because they were thirsty for souls, and Harry happened to have more than one.

Why did the Dementors try to kiss Harry on the train?

According to the Harry Potter wikia: They seemed to be particularly attracted to Harry because, due to his miserable childhood and many bad memories, he was particularly vulnerable to their influence. In other words, the Dementor saw a very tasty morsel, and its gluttony was stronger than its discipline.
