Possible Meanings Of Suicide In Dreams
To dream that you commit suicide can represent your desperate desire to escape from your waking life. You may be harboring feelings of guilt that you cannot get over and thus turning the aggression on yourself. You need to start approaching problems from a different angle. Alternatively, the dream may suggest that you are saying good-bye to one aspect of yourself and hello to a whole new you. It is symbolic of a personal transformation or a new stage in your life.
To see someone commit suicide in you dream highlights your concerns for that person. Consider what characteristics and qualities in that person you may be trying to "kill" and annihilate in your own self. Perhaps you hope that you are not like this person and are making attempts to get rid of those traits within your own self.
