Most Bizarre Dream I've Ever Had

[Horuseus]

Seeing another kidnapped typically represents repressing the characteristics of the individual in question within yourself, which in this case is the inner child. Requiring the bathroom or 'relief' indicates you wish to relieve/purify/cleanse yourself from whatever particular burden you may be feeling emotionally or psychologically relating to that aspect of self. Seen as you inquired as to whether the man was a father appears that the burden in question is related to a parental or authoritarian figure in your life (It may be worth regressing back to the time).

Voluntarily requesting you be shot prior to relieving your burden indicates that you choose to instead inflict self punishment for that scenario which occurred, rather than to 'let go'. Being shot in the stomach and dying indicates a need for a fresh start and that the issue primarily revolves around the solar plexus, or that pertaining to 'I' in relation to others (Self Identity).

Edit: Of course, it's worth noting that dream symbols are unique and tailor-made to the individual, though there are common attributable themes and universally shared archetypes (Personal supercedes however), so Ymmv.
