Can someone else’s dream be a sign from God?

Hey so 2 days ago I wrote a song. I. 24 f and always wanted to be a singer but life got in the way I always write little lives of songs but never pursued it. 2 days ago I wrote a song that was personable and I never felt this good about one in a while. Today I get a text when I woke up from an old friend saying I was in her dreams singing on a stage and literally said the exact lyrics I wrote in my song. She said I was all dressed up and it was a while performance. What does this mean?? I’m not spiritual and I believe In God but I just need some insight on dreams and connections . Because this is crazy. When I tell you she literally said I sing the exact lyrics that I wrote the night before ! And I did not show these lyrics to Anyone. Is she psychic I have chills still
