Huff-puff, the sound of my breathing filled the air. I could barely move with my arm bound to my sides with the weight of body pushing against the walls. I attempted to shift my weight to my right and successfully freed first my left arm and then my right.
The "ceilings" was low, if I was anymore claustrophobic I would have no chance of getting out of this hell. Gathering all my remaining energy, I pushed onto the lid that enclosed me , without managing to budge it open.

Yet i feel a certain weight resting upon it.
I uncomfortably pulled up my knees against my chest and put my feet against the  cover which felt to be made out of lumber. I felt cold water droplets rolled down my body as I kicked as hard as I could.

Crack crack.
The weight now rests upon my body.
