2 What is it?

Kun asked Yangyang if he saw any ghost and looked towards the Villa and saw it was so mesmerising, a pice of art they couldn't put their eyes off it. TY took out each and everyone's back pack and saw the villa but he wasn't much surprised and just thought in his mind saying "what's so great about it? well its beautiful, i wonder whose house is it?" and opened the gate of the villa as soon as he pushed the gate with great force to open, winds blew, sand storm for a while. They couldn't open their eyes due to sand storm and stood there covering their eyes. After a while NCT 127 and NCT Dream arrived and the storm ended soon. WayVs were relieved seeing the storm stop and the other team but there TY found it weird and felt like deja vu. While they were getting in looking around, a lightning and a thunder stroke. TY ordered them to get in the house soon and look around some other day. Soon the rain begun to shower. As they couldn't go out the house itself was so big that they looked around inside the house and saw there were twenty-eight rooms and bathrooms in each and every bed room, three big dining halls. The house was so big and they looked around the house more in depth and they found that there are three gyms, two instrumental room and two dance practice room. They were amazed it and thought there might have been a big family who lived here. There were five great cooks in them they were Kun, Charlie, Jeffrey, Billy and Ten. Taeyong was the leader of the whole group sonhe helped the cooks and asked Mark and Yuta to look after the remaining members. They practiced dancing and played games in the dance practice room for hours. After hours they were finally called for dinner and there were so many delicious dishes to eat so they all sat together in the dinning hall and ate heartily. After they finished their dinner they waited for each other in the corridor downstairs. After every one finished their mean, they are to go to their bed to sleep and while they were going upstairs in their bed room to sleep, Andy, the youngest member of the group was very sleepy so he walked faster than others. While he was walking upstairs he saw his bedroom, as he got the nearest one, he became excited and was almost to run but just then someone pulled his legs and he fell down. His teammates were just talking about how great it is.....,etc and saw Andy fall. TY hurrily went to him and asked if he was hurt and he got hurt on his elbow. Andy was extremely angry with the fact that someone prank on him by pulling his leg and making him fall. Not caring about his wound he said to TY that someone pulled him but everyone was far away from him when he was walking, his bandmates were walking slowly while having a conversation so everyone denied that someone pulled him and Peter told that he was running that's why he fell down. Andy immediately denied that he was running and said I wasn't I was almost to and kept on denying. Peter told again "maybe it was ghost who pulled you" hearing that Andy got scared and believed it was ghost and was about to cry just then TY stood up and took him to his bed slowly he brought first aid and put cream on his wound. After putting on cream he was about to leave but Andy asked him to stay a bit longer. Putting Andy on sleep TY also fell asleep sitting on chair. After some hours TY woke up and went to his bedroom. While he was going to his room also looking if his band mates has slept. After making sure everyone was asleep he was returning back and going to his room just then he felt like someone was staring at him and was almost to reach him just then he felt his head heavy due to low light and was about to fall but then he slowly leaning on wall he walked to his room and slept. He couldn't sleep and was thinking what was it because he felt it so real. Thinking about it he fall asleep.
