Tedium

Thump thump
It was the sound that woke him. His eye were caked shut with sleep, they didn't want to move. He slowly worked his mouth, his lips were crusted and cracked. He was painfully obvious of thirst. He needed something to drink, something strong.
Thump thump
There was that sound again. "What could possibly be making that sound?" He mumbled aloud. Or at least tried to. His tongue was thick and dry, like sandpaper, it didn't want to move. He slowly forced his eyes open. The light was bright, but not blinding. To anyone else, they would have probably said it was dim in the room, but in his current state, it was bright. Slowly his eyes begin to focus, make some sort of coherent sense out of the sights he saw around him.
Thump thump thump thump.....
The sound was incessant now. Like someone knocking. He peered around the room. He had no idea where the door was, let alone where he was. It might have resembled a hotel room at one point, but that was hours ago. Lots had happened since then.
Finally able to focus, he slowly raised  his head. Holding himself on one elbow, he waited to see if gravity was going to work this time or not. There had been occasions when gravity hasn't worked.
Satisfied that everything was normal in the universe, or at least gravity in this particular incident, he slowly pulled himself into a sitting position.
Silence.
The knocking had ceased. He wasn't entirely sure when this had happened, but the quiet that ensued was greatly welcome. He decided that he didn't want to know. But what he did need to know is where he was at.
