Grandmother

I had a dream about my grandmother last night. She passed away almost a year ago and I miss her a lot. In the dream she was living in a fancy apartment building that had shops on the ground floor, like a hotel. We were down there buying buttons and she picked out a beautiful one for me. I said that she should be getting home, but she said that she wanted to go with me. I called my mum to check if that was okay and when she said yes, we took the lift down to the garage where my car was parked. Then I woke up.
Before she died, at a time where she wasn't very well and death was in the cards, I asked her if she had had a good life and she replied:
-The best I have ever had.
