Comfort?

At youth one night we were told to picture God and what we thought Heaven would look like. And when I did I saw a huge throne and God sitting there and he pointed down beside him and there standing beside him was my grandmother smiling at me. She came over and gave me the biggest hug, and it wasn't like a normal hug it felt different. Like she was really there just holding me. Then next the thing you know everything that i saw and felt was gone. Just like in a blink of an eye...I don't know why it happened and then just went away like it did? It still confuses me. But maybe one day it will make sense? And if it doesn't that's okay, I guess? But time will tell. I do wish it did make sense.
