Dreams involving well-known figures, such as Millie Bobby Brown, can often symbolize aspects of yourself or your experiences. In your case, dreaming of treating a patient who is behaving in a distressing manner might reflect your feelings about your work in hospice. It could signify concerns about the emotional toll of your job, especially when faced with difficult or unsettling situations.

The act of the patient eating and trying to smear poop on you could represent feelings of helplessness or being overwhelmed by the challenges you encounter in your role. It might also indicate a fear of being negatively affected by the emotional burdens you carry from your work.

Having your brother in the dream, helping to calm you down, suggests that you may rely on your support system during stressful times. This reflects the importance of having someone to turn to when you're feeling anxious or overwhelmed.

Overall, this dream may be urging you to address your feelings about your job and to seek support when you feel anxious or stressed. It could also be a reminder to take care of your mental health in a demanding profession.
