They all appeared at your place 😱

It was a Saturday morning in winter, you were sleeping in your cozy blanket as usual (you had a three-story detached house, and for the time being, you lived alone), and then you felt something fall to the floor with a crash and heard a few strong words. You opened your eyes and saw the following picture: the characters from the movie x7 and the animated series were lying and sitting on the floor in various positions. These were two universes, namely Harry Potter. It included: Harry Potter, Draco Malfoy, Hermione Granger, Pansy Parkinson, Ron Weasley, Blaise Zabini, Ginny Weasley, Luna Lovegood, Neville Longbottom, Fred Weasley, George Weasley, Bill Weasley. Fleur Delacour, Charlie Weasley, Percy Weasley. Sirius Black, Remus Lupin, Lucius Malfoy, Narcissa Malfoy. Bellatrix Black, James Potter, Lily Potter. Severus Snape, Mythadora Tonks, Dudley Dursley, Petunia Dursley. Vernon Dursley. Voldemort, Molly Weasley. Arthur Weasley. Regulus Black. Peter Pettigrew. Andromeda Tonks. Ted Tonks and the Fantasy Patrol. It included: Alena, Varya, Masha, Alice, Vasya, Sasha, Morok (Vlad), Art, Zart, Dubomir, Zeina, Zlata, Ottley, Hurley. Their animals: Dracosha, Shushik and a cactus. You sit up sleepily and rub your eyes. *
— Who are you?* you ask, confused.
