The Feeling of Death

So I had a pretty graphic dream the other night about my grandmother on my mom's side...I swear it seemed so real.
I was out on the field somewhere, at Stony Brook University, they were having some sort of "field day," kind of like the ones they have when you're in Elementary school. It seemed unreal; everyone around was happy, and paying very close attention to what was going on. There was also organization in the rows and rows of people that were sitting indian style on the lawn (either waiting their turn to take part in an event or just watching).
I ended up arriving late for some reason, and as I approached where my family was sitting on the lawn, I decided to sit next to my grandma..
I don't think I should go on with this dream anymore...
Atleast I made a note of it to myself I guess.
Insane..
