Dreaming of death

Sa

My mom is 79 years old. I recently moved out a year a ago and moved 3-4 hours away. My brother does my mom food shopping and errands when he can get time off of work. He can’t always go so my mom asked her friend to go for her if it’s something small and local . My mom friend has severe asthma. Just walking down the street gets her out of breathe. I had a dream that she had an asthma attack in the middle of the street and just died right there and laid for hours. And my mom calls me to tell me they found her and she was was wearing her keys and had the supermarket ad in her hand. I can picture her very clearly. Can This mean anything ?
