A large object appears in the sky, moves in a strange fashion and vanishes after abducting a lone PC. The PC is later returned unharmed, but has several traits changed on his character sheet, no memory of the event and continually has strange dreams about goblins in space wearing lab coats and holding glowing wands.

I’m inviting anyone who has a short plot , set in some sort of wilderness, to post it here.
Your average posse of adventurous types is hired by a wizard to stop the attacks on a small village.
A slow, stupid creature that crawls onto people and latches onto them, often on feet, hands, and other extremities, numbing down the area and slowly feeding on it. It's easy to avoid while awake, but nearly impossible to remove once attached. Many an adventurer has been forced to hack off an arm or leg after waking with a Stoneleech wrapped around it. Sleep with one eye open! (This idea came from "Wizard's Rule")
