Dreams featuring animals, particularly in distressing situations, often reflect our feelings about responsibility, care, and nurturance. In your dream, the cages and sheds full of pets suggest that you may have aspects of your life or relationships that you feel are neglected or that you have overlooked. The fact that the animals were dessicated and starving could symbolize feelings of guilt or anxiety about not being attentive enough to those responsibilities.
The act of changing their bedding and providing food and water signifies a desire to make amends or to nurture aspects of your life that have been neglected. Seeing the animals begin to take a more normal form as they are cared for can represent hope and the possibility of revitalization in your life or relationships when you take action.
Feeling guilty in the dream indicates a strong awareness of your responsibilities and the need to address them. This might be a sign that there are areas in your waking life where you feel you need to put in more effort or attention. It could also imply a need to forgive yourself for past oversights and to focus on positive actions moving forward.
Overall, this dream encourages you to reflect on what you may be neglecting in your life and to take steps to nurture those areas. Consider what aspects of your personal or professional life require more attention and care, and how you can begin to address them.
