If you saw a loved one in the afterlife, what would be the very first thing you’d say to them?

i don't believe in an afterlife but i have dreams about people who died and I say the most random things / questions to them. Last night in a dream i talked to a deceased relative as we were getting into a car to drive during a snowstorm.

I asked him if he could drive in this weather. We didn't crash in my dream so I guess it the answer was yes . There was so much snow in the parking lot in my dream that a boat came in from the ocean with food on it for the grocery store we were at-- as opposed to an 18 wheeler with food.
