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.
Everyday 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.
