To see yourself or other people being cured in your dream is a good omen and foretells evolution, progress, a great improvement in your waking life. You will be able to accomplish tasks, deal with responsibilities and problems as difficult as they may be. Also, you will attain most of your goals.
Curing and getting well dreams are highly popular among people who suffer from health disorders - in this case, such dreams may be compensatory (the person desperately wants to be healthy again and constantly sees it in the dreams) or premonitory (physical healing will come in the waking life).
Seeing people being cured from mental illnesses are also a good omen and announce happy and joyous times to come into one's waking life.
