Down
Down, in the sense of lying on the floor, or squatting, suggests several things depending on the context. It can be feeling without power or a loss of power. It can suggest dropping activity, resting, becoming passive and open to inner feelings and intuitions. Of course it can show rest, recuperation, an interlude from activity. See: Descent.
As can be seen from the enormous number of ways we use down in our speech (see idioms) it depends on the way the dream present it.
But things like going down in water, a cave or the earth or even your house is usually depicting getting deeper into your own nature. This may at times be felt as threatening or scary. See The Life Will
