The Spectral Trees

Things PCs find in a creepy forest. Roll (d8):

1. A small pool of liquid silver. 
2. When cut, trees bleed what looks like human blood. 
3. Plants that begin to sing lullabies in unison. Roll d3: (1) Lullabies are a sleep spell. Will Save DC15 or PCs fall into a deep dream-state for 1d3+1 hours, unable to be awoken except by vigorous means. (2) Plants sing 1d3 true rumours about the forest. (3) Plants sing 1d3 false rumours about the forest. 
4. A lost person who can’t recall their identity. One of the PCs knew this person from their past and was certain they were dead. 
5. A colony of fairies living in the canopy of trees who can heal wounded PCs with Lay on Hands. 
6. Absolute and utter silence. Sound is absorbed by the forest, does not travel, nobody can hear each other speaking – the PCs are unable to hear any noise whatsoever, except their own heartbeat. 
7. A perfectly carved stone stairway leading underground. 
8. Several mutilated corpses are chained to a tree. There are strange geometric symbols growing on the trunk.
