my wife was pregnant. and there was a cat which was dying.
In dreaming about your wife being pregnant, it can symbolize creativity, new beginnings, and the gestation of an idea. This suggests that you may be subconsciously anticipating the birth of a new project or idea or a new phase of your life.
The symbol of a dying cat in your dream may represent something that is not working out for you or something in your waking life that you are losing. It could also mean that you are experiencing a loss of independence or feeling vulnerable and helpless. This might indicate that you are going through a change that you see as threatening and may need to address and acknowledge your feelings regarding this change.
