Are there really ghosts and the supernatural? (Starter)

It was already dark. The rain drummed against the window and in the distance silent lightning bolts lit up here and there the sky.
Deep in thought, Young sat at his desk staring at a blank sheet of paper. His thoughts were confused. A chill ran down his spine as he tried to remember.
Another flash of lightning flashed across the sky and this time also lit up the room in gleaming white. This was followed by a loud clap of thunder. Young winced and turned around, startled.

His bed was behind him. San was already fast asleep. He had to smile for a moment when he saw him like this. San looked so carefree and relaxed. Even in his sleep he smiled and sent out a comfortable calm. Actually he was like that. Or rather he was until a week ago. He thought he had seen something after a concert, but to this day he couldn't explain what it actually was. Young wanted to remember and yet his brain tried to block the memory.

Instead of lying down with San and trying to get some sleep, which was also days ago, he went into the living room. There he sat down on the couch and started staring out the window again.
Lightning flashed faster and brighter across the sky. The thunder was getting louder too. Until, the rumble became a loud growl of a monster.
Young flinched again, this time the memory snapping back.

It was now about a week ago. Ateez had just successfully completed a sold out concert. Everyone was exhausted and equally euphoric. It was already dark when the boys walked to their bus. Even then, Young noticed something. Something was moving in the darkness and it looked like wafts of fog were forming. He quickly dismissed it as a pipe dream. Together they got on the bus. In the beginning they were still joking around but little by little the boys got tired. Young was the last one left awake. More or less. He yawned and felt San's head fall against his shoulder.

He was about to close his eyes when something caught his attention out of the corner of his eye. There he was again, that misty shape in the dark. But how could that be? They were on a moving bus and it didn't look like fog was really gathering. Young closed his burning eyes and turned a bit to San. Carefully he snuggled up to him.
An oppressive feeling came over him. His heart was racing and his hands were bathed in cold sweat. Maybe it wasn't a good idea to watch a horror movie before the concert.

Then he fell asleep. But only for a brief moment, it wasn't even 30 minutes. He looked around sleepily. The rest of the boys were still asleep and the bus was still driving. They still hadn't arrived at their dorm. But it probably wouldn't be long. To see where they were, he looked out the window again. He knew the area.

Relieved, he took a deep breath and let it out with a slightly hidden sigh. But the relaxation that was about to spread through his body came to an end. Because again these wafts of fog appeared right next to the bus. And this time it wasn't just swathes. More and more a body formed and a pair of glowing eyes.

The blood froze in his veins for a moment as the outlines became clearer. Young wanted to wake San but he couldn't move for fear. That wasn't real. That couldn't be real. His mind was definitely playing tricks on him, he tried to convince himself.
This thing had human traits. When it realized that Young was paying attention to it, this creature made a direct swerve towards the bus. There was a brief rumble as if something had hit the side, and from the front a curse could be heard from the driver. This light blow woke up the others and asked sleepily if they were already there. From the front, the voice of the driver sounded again that it would only take 20 minutes.
Young tried to calm down and held San's hand tighter. He just wanted this trip to be over.

After 20 minutes of hidden panic and 7 hyperactive bandmates, the ride finally came to an end. He got off the bus as quickly as possible. He breathed in and out the cool night air a few times until he felt calmer.
Now he had an explanation ready. The stress, the tiredness, hunger, insomnia and the horror movie. These were all the triggers for this thing he imagined. He laughed, yes it was just an illusion. There weren't any ghosts or anything like that. Then he felt San put his arm around him and pulled him with him.
As they passed the bus, he stopped abruptly. Right where he saw it on the side of the bus was not just a deep dent, there were also deep scratches as if something had tried to rip open the bus. His face turned pale and he was glad that San just dragged him along.
That was a week ago now. Since then he hadn't slept so well as at all. He also didn't want to leave their dorm.
Were there ghosts and other unnatural beings? Or was he going crazy now. He urgently needed answers, but where could he find them?!
