The world in which we live is known as another word in another world that is not a place to some, but a real place to others, to those who have read and seen and have stuck with it to the very end. Our world is so mundane compared to that of this other world of which I speak. It may not be a physical place, but it certainly is a place in our hearts and minds. The world of which I speak is the world of Harry Potter. This list is the top 5 articles I think are what makes the headcanon of the Harry Potter series so interesting. Without further adieu, this is the top 5.

1. Crookshanks was Lily and James Potter's cat

Now this one is a fairly recent one, and though there are debates about the truthfulness, and Rowling herself has never confirmed nor denied this, it is certainly an interesting theory. "How so", you may ask? Well, as we see in the third book, Hermione says that he had been in there for "ages". Now, this can either mean one of two things: 1. Crookshanks has been in the Magical Menagerie since 1981 which was the year the Potter's were killed (save for Harry), or he simply had been in the Menagerie for some time, and is not related to the Potters home in Godric's Hollow whatsoever.

2. All 7 years of Harry's time at Hogwarts and on the run was nothing but a dream

Now this theory is a weird one to accept, however the theory itself says that all six years of Harry's magical education is nothing but a dream while he continually is abused and neglected by the dastardly Dursleys. Though this is a weird one, it could have totally been possible, but alas for us Potterheads, it was not, and we got rewarded with the series of a generation.

3. The Dursleys live with a Horcrux

Now this one is certainly far fetched, as it is not entirely possible. However, when Ron wears Slytherin's locket in the final book, he becomes a terrible person characteristically as he is much more headstrong than Harry or Hermione whilst on the run from the Death Eaters. While Harry did not wear a Horcrux at any point in time with the Dursleys, we find out later, Harry WAS a Horcrux, albeit unintended as Dumbledore explains in the later books. This would explain why the Dursley family was so horrible to Harry.

4. Hogwarts Students

This theory is based on the years of the first Wizarding War, which was the 1970s until 1981 when Harry "broke" Voldemort. The reason that Hogwarts has about a thousand students but Harry's year is abnormally small, no more than probably 24 or so students, is due to the fact that people were afraid of the Death Eaters and Voldemort, and therefore did not want to have a lot of, if any children.

5. Rowling is actually Rita Skeeter

As the final theory, this is perhaps the most interesting one, if not the best one. Rita Skeeter, the famed witch journalist for the Daily Prophet, could potentially be Rowling herself based on the theory that after far too many fabricated stories, Skeeter was forced to be banished from the wizarding world, thus snapping her wand in half, joining the Muggle world under the name J.K. Rowling and goes on to write the books we know and love today.
