A dream about my grandma..

My grandma passed away few yrs ago at the age of 80+. I'm not very close to her and we didn't talk much too. I only visit her once or twice a year during CNY or sometimes when I balik kampung.

Few days ago, I had a dream about her. She was in her fifties and she's waving at me, smiling too.. In the dream, I waved back and I had this feeling that this is the last time I will be able to see her.

What does this means? She's going to a better place (since she dress nicely and smiling so I assumed she's going to a better place..)? I do hope so, I really do...
