Dream About Grandmother And Hospital Bed

I was in the downstairs apartment at my old house. There was an empty hospital bed with my moms name on it. Then I saw ny brother and ex boyfriend. My brother said to me "I'll keep it hot for you." Then my ex boyfriend said "hurry up." Then I walked into my deceased grandmother's bedroom and suddenly the dream became very vivid and graphic like seeing something in waking life. My grandma was sitting in a chair with her head down. She was wearing an old black dress, her glasses and black shoes that she used to wear when I was a child. She looked healthy, but was not moving or talking. The dream looked very real. Several weeks later in real life, my mother sudden had to have open heart surgery. The dream was Luke a recognition of what was to come.
