To see an upside down crucifix implies that some aspect of your life is in disarray. You are not sure what to believe or what is right anymore. Things are not always what it seems.
Alternatively, an upside down crucifix is symbolic of the pope.
To see a crucifix in your dream is symbolic of new life, spiritual guidance, and liberation.
The dream may serve as a connection with your inner Christ/love consciousness.
Alternatively, it represents your difficulties and hardships. Do you feel you are being crucified for something occurring in your life?
