Your class was organised for a trip to a museum. After a long and tiring bus ride to the other side of the city, you finally reached your destination - an old history museum, which was one of the best and most famous museums ever.
Interestingly, you had never been to this museum before. For the few in your class who loved history, it was the best day of school, but most of them found it super boring. However, they didn't complain, since they didn't have to write a math test because of the museum visit.
Nothing much happened for the first twenty minutes - "Do Not Touch!" signs, the tour guide saying something, cameras clicking here and there. But then, looking at one of the exhibits, you fell a little behind the class - they had already gone to another hall, and you remained here.
Your attention was drawn to a shiny knight's armour that occupied a place of honour in the room. It was so beautiful that there were doubts about whether it was real or just a restored copy.
While you stood there and thought, the knight's helmet suddenly turned towards you with a quiet creak. Before that, he had leaned with both hands on the sword in front of him, which was stuck with the other end into the ground, and now the knight's right hand rose and gave you a small wave with a quiet click of metal...
The Greek statues also came to life, gasping and covering their pale bodies when they realised you could see all their "secrets". Some royals in the drawings started adjusting their hair and clothes. Even the mammoth statue in the other room began snoring in a peaceful sleep.
It looked as if the spirits of this knight, the statues and everyone else had taken possession of the bodies that had previously belonged to them. It was hard to say something about the other spirits, but the knight was friendly and had the strongest aura.
You were the only witness of this chaos.
