The room is bright, cheery room filled with color. Light is streaming in from a large bay window. I am in a large comfortable bed with a beautiful woman.
The forest is large and ancient, primordial even. Dripping with water and life. Verdant trees are spaced close together. There is a faint hint of a rotting core to the forest and it is bright in some places and dark in others.
The path appears to be lined as if the road of an ancient civilization where the forest itself has grown up around it. It makes a straight way through the forest, but the forest it self does not always agree with this and here and there it encroaches upon it blocking its way.
The water appears to be a shimmering silver, as if the metal itself has become liquid and is flowing past. I can see my reflection in it. The river, for that is what it is, stretches 8 feet across and in both directions as far as I can see.
The cup is actually a chalice, a left over remnant perhaps of the same civilization that built the path. The excellent artistry is apparent with fine craftsmanship exemplified in the obviously valuable metal its has been crafted from as well as the ornate engravings etched across the goblet.
The key appears to be a futuristic key card. It looks like it has been well used. It looks as if it unlocks a room to a vast treasure trove or perhaps to a repository where all knowledge is stored.
