"To see someone drowning in your dream suggests that you are becoming too deeply involved in something that is beyond your control. Alternatively, it represents a sense of loss in your own identity. You are unable to differentiate who you are anymore.
To dream that you are drowning indicates that you are feeling overwhelmed by emotions and are in over your head regarding some situation. You need to gain greater control of your life. Repressed issues may be coming back to haunt you. You may be proceeding too quickly in trying to discover your subconscious thoughts. You should proceed more cautiously and slowly.
To dream that you are breathing underwater represents a retreat back into the womb. You want to return to a state where you were dependent and free from responsibilities. Perhaps you are feeling helpless, unable to fulfill your own needs and to care for yourself."
