It is a family room but it is very bright and there are several people in it from all walks of life. It is warm, but very comfortable and has very nice furniture - soft leather couches, lamps of the Tiffany type, and the colors in the room are pastels - very pretty. There are blinds in the windows and all are pulled up so that one can see the ocean waves in the sparkling sea.
It is a beautiful forest and the sun is shining on the trees. It is not dense - if it were the sun would not be visible. It is, so therefore it is bright and one can hear the birds singing and can see them flying around.
The path is leading from the forest and on the other side, one can see the ocean. It is very easily navigated as it is wide and there are wild flowers along it. I think it is not too well traveled, though it is a definite path.
The moving water is definitely the ocean - it is clear, blue, sparkling, and there are gentle waves rolling into the beach area.
Someone left an empty bottle of drinking water - in a sport bottle. It is a plastic bottle and holds about l liter.
The key could probably be a key to someone's house or car. They probably dropped it while walking.
