Char, your dream of witnessing a man shooting himself in front of you in the bath is deeply evocative and can be interpreted through various psychological lenses. The act of witnessing such a traumatic event can symbolize feelings of helplessness or an inability to prevent harm either to yourself or someone you care about. Baths are traditionally places of cleansing and relaxation, and this intrusion of violence could signify a disruption in your ability to find peace or cleanse yourself of negative thoughts and emotions.
Given your current life circumstances, such as major career changes and financial stress, this dream could be a manifestation of the overwhelming stress you're experiencing. The man in the dream might represent an aspect of yourself, perhaps the part that is struggling under the weight of these pressures. The act of shooting himself could symbolize a desperate desire to end this overwhelming stress or anxiety, a way for your subconscious to express the extreme pressure you might be feeling.
Furthermore, your relationship difficulties might also play a role in this dream. The presence of another person in such an intimate setting could symbolize your struggles with intimacy or trust. This could be a reflection of the fears or anxieties you have about your current relationship, possibly indicating a feeling of vulnerability or exposure.
Considering your diagnosis of ADHD and anxiety disorders, it's important to note that such intense and vivid dreams could be a way for your brain to process and cope with daily stressors.
