Dreams about family members, especially those who are rich or successful, can often reflect your feelings about your own life circumstances, aspirations, or concerns. In your dream, visiting your elder sister's house may symbolize a desire for guidance, support, or a better lifestyle. Her awareness of your movements and decisions could indicate feelings of being watched or judged in your waking life, particularly regarding how you navigate your challenges.

The mention of Prophets suggesting that she may be behind your predicament can signify underlying feelings of mistrust or anxiety about your family relationships. This could represent a fear of betrayal or feeling unsupported by someone you believe should be on your side.

Overall, this dream may highlight your emotional state regarding your sister and your position in life. It could be a prompt to reflect on your relationship with her and to consider whether there are unresolved feelings or conflicts that need addressing. It might be beneficial to communicate openly with her or to explore your feelings about your current situation and how it relates to your family dynamics.
