Dreams involving deceased loved ones often reflect deep emotions and unresolved feelings related to loss and grief. In your dream, the return of your dad symbolizes a longing for connection and comfort. His poor condition and eventual passing may represent your fears about losing him again or feelings of helplessness in the face of his absence. The act of catching him as he almost collapsed suggests a desire to support him and a wish to keep him close, highlighting the importance of your relationship.

Wandering through the hospital symbolizes your search for closure and understanding. Not knowing where to find him could indicate feelings of uncertainty or confusion in your waking life regarding loss or other significant changes. The emotional journey you experienced in the dream illustrates the struggle of moving through grief while also cherishing the moments you had.

The leopard in your dream may represent hidden aspects of your emotions or instincts. Its repeated hiding could symbolize your reluctance to confront certain feelings or memories, or it may suggest a need to explore parts of yourself that are currently out of reach. Your mother’s comment about the leopard being beautiful may reflect the idea that there can be beauty in grief and the complexity of your emotions.

Overall, this dream is a profound expression of your feelings about your father, grief, and the longing for connection. It’s important to allow yourself to process these emotions in your waking life. Consider talking to someone about your feelings, whether it's a friend, family member, or a professional, as sharing can often help in navigating grief.
