It always happened when he stayed in one place for too long. It happened sooner when he knew he slept in a building where other people were staying. He was sure the only reason it hadn't happened before now was because he didn't think he'd actually be staying in the tower.
Now he had his own damned floor with Tony insisting that they figure out his big, green problem. And then Tony insisting that he trusted the Hulk and had no fear of him. It was too much and his mind refused to allow him to relax.
Sure, the night had started off easy enough. His usual worries followed him to the bed and he settled down to sleep thinking the night would be just like any other night.
How he was wrong.
He didn't even realize he was dreaming. All he knew was that he was Hulk and Hulk was angry. Hulk was scared. Hulk was in a place he didn't recognize except for the lingering stench of alien that attacked Hulk. Hulk had to get away. Hulk had to run.
First, Hulk had to destroy.
Hulk ran through the building, falling through floors and then climbing up walls. Hulk smashed walls and heard screams. Hulk heard the building talk and the metal man yell. Hulk reached the top and turned, but the metal man was not there. Metal man was not in metal.
Man with glowing chest stole metal man. Hulk ran toward him, yelling. Hulk continued until both Hulk and glowing man fell off the building.
In his bed, Bruce jerked awake with a strangled yell. He was sweating and his breathing was fast. There was no destruction in his room, there were no warnings going off, so it was a dream. A dream. The other guy hadn't done anything. He hadn't done anything.
He got out of bed and went to open the nearest window, taking a deep breath of fresh air. If this was going to happen often, he wasn't sure how he could handle it. He would eventually, but until then, he would just need to get used to little sleep.
He'd wait a few hours before leaving the room. At least then he could pretend he got some kind of sleep.
