What does it mean when you dream about decay?

Decay may symbolize the degradation of a situation. More positively, it represents the death of an old situation before rebirth into a new state. Other associations come from such common idioms as “rotten apple.” (See also Maggots).

decay

[di′kā]
(geochemistry)
(materials)
To undergo decomposition.
(nuclear physics)
(oceanography)
In ocean-wave studies, the loss of energy from wind-generated ocean waves after they have ceased to be acted on by the wind; this process is accompanied by an increase in length and a decrease in height of the wave.
(physics)
Gradual reduction in the magnitude of a quantity, as of current, magnetic flux, a stored charge, or phosphorescence.

brown rot

A fungus that destroys wood cellulose, leaving a brown powdery residue behind.

decay

[Nuclear physics] An automatic conversion which is applied to most array-valued expressions in C; they "decay into" pointer-valued expressions pointing to the array's first element. This term is not used in the official standard for the language.

decay

The gradual reduction of strength of a signal or charge.
