Remembering that most people in dreams depict an aspect of oneself, this may be illustrating that we lack pleasure in life or have little to live for in the way of satisfaction; suicide may also be a sign of interiorised anger, where instead of admitting our anger, we destroy parts of our own feelings; may depict business or relationship suicide.
If it is someone we know: Often shows us hoping person will get out of our life; intuition.
Example: In a dream my wife, Brenda, saw a baby that she knew belong to a friend, and a voice from behind her told her the child was ill. Its illness, she was given to understand, was serious, and would need to be treated with a drug taken every day of the child’s life. The reason for this illness and the drug use, she was told, was because in a past life the being now born as the baby had committed suicide using a drug.
I sent an account of the dream to the parents of the baby. About a week later we had a letter from them saying that the letter and dream had crystallised their already existing anxiety about the baby. It had not been feeding well and was fretful. On taking it to the doctor nothing definite could be found but special tests were made in hospital. From these it was discovered the baby was dying. It lacked an enzyme that was needed to digest calcium. To compensate it was given a drug, which it has had to take every day of its life to make up for the lacking enzyme.
