Leaving the matrix

Me and my grandma are walking into a multipurpose room in a school, teachers stop us and tell us there is a funeral in there. We look in and see a huge casket and a crowd of suited people. My grandma asks someone standing against the wall who died, and they tell my grandma that the principle of the school died at 192. My grandma said she was shocked because she knew the man and he had being doing his secrets to live long. Then I see a flash back of him and the man only looks late 50's or early 60's. Then inside the room turns into outside at night with white lattice walls all around and we watch the rest of the funeral even though he's by the food laughing and talking with people.
