Dreams about childhood homes often symbolize our past, memories, and unresolved emotions. In your dream, the guinea pig represents something that requires care and attention. This could symbolize a part of yourself, a relationship, or a situation in your life that feels neglected.

The act of picking up the guinea pig and wanting to care for it reflects your nurturing side and a desire to help those in need. It may suggest that you feel a responsibility to take care of things that are not your direct responsibility, possibly indicating feelings of being burdened or overwhelmed by others' needs.

Your father's presence and instruction to put the guinea pig back in its cage may represent authority figures in your life or societal expectations that restrict your desire to care for or connect with something you feel passionate about. This could reflect a conflict between your desire to nurture and the limitations imposed by others.

Overall, this dream might be inviting you to reflect on your relationships and responsibilities. Are there areas in your life where you feel compelled to care for others but feel restricted in how you can express that care? Consider taking time to evaluate your boundaries and needs, both for yourself and for those you wish to help.
