Dead relative in dream??

Hi everyone! I’ve been told that seeing a dead relative in a dream is a sign a new baby will be conceived…

Last night I had a dream of my Great aunt (she passed 14 years ago… I was 6-7 years old… we weren’t very close from what I can remember) however, I was running around to everybody in my dream asking if they could see her and they were all were saying yes and being so nonchalant about it. Finally I go over talk to talk to her and she stands up and hugged me and says “ I love you so much. I am so proud of you. Big things are going to happen soon big changes are coming.” I remember telling her I love you too and us hugging for a while. I remember walking out of the room we were in bawling my eyes out and my cousin following behind me and asking me how she’s here and then it was weird that she was here because she is dead. My cousin finally talked me into going back inside and as soon as we did I woke up I jerked out of the bed and gas for air like I had to quit breathing while I was asleep.

Fast forward to today, I’m telling my mom and my grandmother about the dream that I had ( this is my grandmother sister).

My grandma goes on to say that she had a dream about her sister two nights prior to this, my mother had a dream a week prior to my grandmothers dream of my aunt in there also. They can’t remember exactly what happened in their dream they just remember talking to her And my mom remembers asking how she was there and why she was there.

Is this a strange coincidence? Or possible sign?
