You’re just as sane as I am
The Great Hall is the first place you visit upon your arrival at Hogwarts each year. It is a vast room, large enough to hold all the staff and students daily as they eat their meals. It is here where the Sorting Ceremony is held at the beginning of the year, and where some exams are held at the end. It is also where the headmaster addresses the school and owls are received.
Located by the main entrance, you must pass the house point hourglasses and enter through the ornate doors. Inside there are five large tables, one for each house and one for staff. These tables have hundreds of magically re-filling plates and cups of food and drink local to Britain and the wizarding world. Above them through a mass of floating candles, is the famous enchanted ceiling which is bewitched to look like the sky outside. It is said to be so mesmerizing that at first many believe there to be no ceiling at all.
The gif of that weather system is called a mesocyclone and it’s normally associated with severe thunderstorms that produce tornados.
and yet 90% of people will go outside to take a look instead of running for shelter.
