A spiritual code may appear in dreams as an unrecognizable language which requires deciphering. It can also be a code of behaviour by which one must live.
Psychological / emotional perspective: To be deciphering a code in dreams suggests that we need some understanding of the ‘key’ to our own or others’ behaviour or that there is knowledge at present hidden from us.
Material aspects: To be using a door code or some kind of numerical combination suggests that we have the necessary information to gain access. Not to know the code or to have forgotten it indicates that we must be more careful in future. This meaning holds good if we do not know the correct code of behaviour.
To dream of code - or coded messages - is a warning against deceiving others. It can also be a warning that those you trust may not have your best interests totally at heart.

A way to locate someone or something for which you have been searching. Make special note of these numbers, and see if you can’t find a waking representation of them.
