What does it mean to dream a pond or water?

It is very difficult to determine the meaning of a dream from a single snippet of information. Dreams communicate through symbols which relate to each other in the environment where the dream takes place. One fragment of one symbol, isolated from its context, has very little significance in any way. For example "a pond or water" could be in an urban park or the Amazon jungle or the Sahara Desert. In each case, the meaning would be very different. An interpreter could create a scenario built on that fragment, but the result would be a product of the interpreter's imagination, not a true analysis of the dreamer's experience.
