When you picture yourself "hanging in a dream," it means you'll need help. It might also be linked to anything you're clinging to in your waking life or something you've discovered to concentrate on.
It might also imply a difficult circumstance. There's a definite impression of hanging troubles out to dry in certain nightmares when the dreamer commits suicide. It is a sign of life’s difficulty.
In a suicide dream, any sort of strangling represents enjoyment and inventiveness. The rope has a "symbolic" meaning and is associated with maturity.
A dream in which a relative hang himself or herself means that one is 'tied up on guilt,' or that troubles are prompting the subconscious mind to be concerned.
