Dreams of teeth are generally assumed to have sexual significance.  This is, however, only to some extent correct. The development of the teeth runs parallel to man's physical development, and simultaneously indicates the process of aging.  If the dream teeth stand for sexual potency, then they also symbolize aggressive tendencies.  Teeth which fall our can be seen as a symbol of general loss of potency.

Should a theft occur, this indicates a loss threatened by lack of attention on the dreamer's part. It may indicate the dreamer's loss of contact with the world about him.

With the image of the toilet, the dream is referring to the natural process (natural also in the psychic realm) of the discharge of the undigested remains of problems which have already been worked through spiritually.

In a dream, the tongue symbolizes the fertilizing and creative side of the intellect.

If the dream takes place in a town or in the home town, it is referring in some way to the dreamer's spiritual home, but in a broader sense.  It is the realm of psychic affairs, formed by coming to terms with the world outside and relating to it.  In the symbolic language of earlier times, the town can appear in dreams as mother figure.

The fairytale situation where the dreamer unexpectedly finds treasure indicates that unexploited talents or potential lie within him and should, like the treasure, be unearthed.

The symbolic significance of the tree is usually the tree of life.  The tree may appear as an image of the dreamer's personal life, but can also refer to the family situation over a period of generations, just as the expression 'family tree' indicates.
