Thank you for sharing your dream with us. Please take everything that I share to the Holy Spirit as He Alone gives the accurate interpretation.
I confess that it was hard to follow some of the content of your dream.
It appears that either you/yourself/church is going through a hard/dark/uncertain time. Some people may be feeling unheard. You need to reflect on what morals/lessons/advice/values that your “grandmother”(either literal or what she represents) taught you and consider implementing it as long as it is Biblical and Spirit-led.
I believe that scene #2 unlocks the full interpretation of your dream. Take it back to the Holy Spirit for clarity.
