I live on a house by a lake with a group of friends that includes people of all ages (though I believe the youngest of us was around 18 years old). It is a beautiful place and we are really friendly. The place is always crowded, though I'm not sure if all the people that show up here actually live here. I'm outside with some friends. We had a chest with jewels and gold, which was some kind of treasure, possibly mine. A group walks up to a rowboat and rows to the lake. When they are in the middle of the water, either they call me or I call them and they throw some jewels back from the boat at me. They were intricate relics - rectangular colorful gems thick as bars of soap, tied together with gold (?) and forming some kind of large rectangular pendants, roughly the size of my palm.

They throw two or three, and just by a glance I can tell that these are priceless. My treasure was nothing compared to it. At the same time, I knew it belonged to us all, but that didn't stop me and a friend from trying to pull off a prank. We pretended we were running away with the stones. The dream gets confusing around this point, but in the end it proved to be a bad idea. Our friends got angry at us for the prank, but at least we didn't get into any real trouble. Some denizens didn't even get angry. I remember meeting an elderly woman who had gathered a group of also elderly friends in a room. They were as friendly as ever.

Later, I'm meeting this thin black depressed-looking boy who was a friend of mine. I meet him outside a building and we head in, meeting with two other friends (one of them, apparently, had helped me with the prank, before). Turns out he was sad because he was having trouble with some girl he liked. He didn't know what to do to be with her. We were trying to help him, though I don't remember how. We enter the place and get a table at a bar/restaurant. I finally notice my friend from before looks an awful lot like Barney Stintson from How I Met Your Mother (Neil Patrick Harris), albeit a younger version of him. It wasn't just looks, either - he acted a lot like him too. We talk:

Me: Dude... You know How I Met Your Mother? Do you watch it? [I suddenly remember talking to him about it before. Apparently he had seen more episodes than I did.] Oh, yeah, you do.
Friend: [Cutting me]- Yeah, I do.
Me: Has anyone ever told you look like Barney Stintson?
Friend: I know the guy! We worked together in the past, remember I told you?

I did remember him telling me about it before. He explains that some years before he worked with Barney (or was it with Neil?) and he taught him everything about being like him.
