Dream of Friend Who Died

Last night I dreamed that I was in a room with people I know, including the mother of my friend who died in February. I was looking in a full length mirror and my friend appeared there. She looked like herself and seemed ok. Her mother was sitting at a round table next to the mirror so she didn't see into it or know what was happening. I asked my friend if I can tell her mother that I see her. My friend nodded yes and when I turned to her mother to tell her, my friend faded away.

If anyone has info on what this could mean, I would appreciate it. My friend ended her life in February after going through some difficulties. It has been hard since then, I still think about my friend
