Fantastically weird

Yesterday I had the most insane dream. Now, I am a person that normally has some pretty crazy dreams. I read an article that there are some people that dream all the time, and other people that seem to never dream. I'm one of those people that has very vivid dreams all the time. One time I had a dream that I was flying a plane. I hate planes, so that was weird.
Now back to my story. I had this crazy dream last night that I was on a desert island with palm trees every where. There were coconuts falling down and I grabbed one and tried to crack it on a rock. And as I did, a man popped out from behind a tree. He started walking toward me and as he did, he introduced himself as my grandfather whom I've never met in real life (he died while I was in high school). He told me to come with him, so I followed him and as I did, we all of a sudden were in the middle of a Chicago Chevrolet dealership. (This is not as odd as it sounds as he really was a car salesman at one point during his life.) And as we were sitting at this Chicago Chevrolet dealership, my grandpa tells me to pick a car. So I climb into one that looks a lot like the car that I drive now. He hands me the keys and I drive away from the Chevrolet dealership and my grandpa.
Then, I wake up. Fantastically weird, isn't it? I don't really believe that dreams have meaning, though, but if you'd like to interpret for me, I'm willing to listen.
