The first thing you become aware of is a touch of vertigo, with nausea, and a pounding headache. After a few moments, however, these sensations fade, leaving you cautiously touching your head to see if the pain is really gone. You open your eyes....
Traces of panic thread inward. You blink, and suddenly you can distinguish shapes. Color, green, all green, in a riot of variations sweeps into what you see. Sound bursts inward, awakening a phantom throb of the headache. Slowly things become clear, or rather somewhat more clear. Massive trunks surround you, a dim glow of twilight green filters down from the shadowy branches above. Birds, frogs, insects, many throats give voice, creating a constant ocean of sounds.
An odd, somewhat unpleasant smell reaches your nose. It creates a heavy tang upon your tongue. You are laying on your back on a large patch of moss in a crook of roots at the foot of a giant tree. Above you on the trunk a mark that looks suspiciously like your up-side-down imprint is burned into the shelves of fungus growing there, though the tree appears superficially undamaged.
You are entirely alone.
