I often dream of my aunt who passed away too. She often appears in my dreams when I am sad or is having problems. She's usually a few meters away and just smiles. Before she died, she also often tells me that she dreams of my grandma and other loved ones who passed away too. By the time she got really sick, my grandma often visits her in her dreams. Sometimes she often confused dreams with reality because they seem so real. My mom also experiences the same.

I always believe in the supernatural world. I think your grandma is trying to comfort you. Sending you hugs! Hope you feel better soon.
