Jim frantically tried to get out as he started to realize that this wasn't just a cavern, but he was actually inside some strange creature!
He struggled at the opening he'd come though, but all that he'd succeeded in doing was covering himself in the slime. His clothing started to fall apart as it got more and more damp, but oddly his skin felt normal. The stuff wasn't burning him, it actually felt kind of good.
As the last of his clothing fell away, Jim sat down, strangely tired and content. His flashlight fell from his hands and then clicked off as the fleshy walls closed in around him. At the same time, the space around him began to fill with fluid. He thought he should panic, but he started to lose the ability.
Finally, in the dark, he entered a strange state of semi-consciousness. He found himself wondering how this place was, and what it was for. He knew now that he was in a womb, he could hear his new mothers heartbeat, he could feel that his body was different, though he couldn't tell just how.
Why would the creators of this place have done this? What did they turn people into? Was this how they preserved the knowledge of their tribe, by being reborn? Or was this a natural place they tried to block off?
All at once, the water started to drain away, and Jim felt himself pushed out. He knew that now at least some of his questions would be answered.
