I had a dream about my best friend's grandma before I found out she died?

Last night I was on Facebook, and I am friends with my best friend's mom on there, and I saw someone post something on her mom's timeline saying, "I am so sorry for your loss, my condolences are with you and your family." I called my best friend, but she didn't answer, so I texted her and asked her if someone in her family passed away, and if everything was okay. Before she answered my text, I had fallen asleep... And I dreamt of her grandma... In my dream I was over at my best friend's house and I was in the middle of a big crowd of people I knew, then I saw my best friend's grandma in the distance. She looked pale, and sad, and I was instantly excited when I saw her, and wanted to go over and say hi to her. But as I approached her, I felt like something wasn't right. I felt very sad, and hesitant... Right as I made my way over to her, my phone woke me up, and my best friend texted me back saying her grandma passed away... And it was the one I dreamt about... What does this mean? Why did I dream of her before I knew she passed? This was the first time I had ever dreamt of her. I grew up with my best friend, and I have known her grandma ever since I was a little girl. She always loved me and my best friend very much.... Any answers are helpful. Thank you.
