Dreamt that I missed my Grandmother's funeral, that I attended when I was 16.

Hello, I woke up after I dreamt that I missed my Grandmother's funeral, (so did my Mom who is now her only living child). However we attended my Grandmother's funeral when I was 16, and all of my Mother's 7 living siblings were in attendance as well. I am 43 now. In the dream, I was angry, hurt and upset that my elder cousins were not considerate of my Mother being in attendance.
