What are YOU doing in my dream?

I had a weird fragmented dream.  I was visiting Guam, only for whatever reason, in my dream Guam was a big campsite field with all kinds of people living like refugees or hippies or squatters in general genial chaos.  Lots of old friends, living in tents with new families, sunshine, grass, and clothes everywhere.  The dream shifted to an apartment or hotel room, where I was rooming with someone.  In my dream, we were best friends, or maybe more, and I knew her intimately.  She was taller than me, and very thin, almost androgynous, although I knew she was female.  She had a dark complexion and almond eyes like natives of Guam, maybe a bit more Asian, but her skin was the coppery tan of Polynesia.  She had long straight hair, but it was sort of cut to look shaggy and raggedy on purpose.   I was under the impression that we were getting ready for bed, so I was naked and totally unselfconscious, puttering around the room.  I recall dimming the lights, and closing the blinds, and preparing to sleep in my bed.  Even though I was nude, there were no sexual feelings, and we were sleeping in separate beds.  She suggested that I get dressed, because we had plans, that I'd probably forgotten about.

I quickly threw on clothes, and moments later, our hotel room filled with people.  People that in my dream, I vaguely knew, no faces, just a press of humanity, noise, the hum of conversation, music.  At some point, I was trying to find something in my backpack. It was my enormous LL Bean backpack that I had in my late teens.  And something was lost, something I wanted to eat, like beef jerky, or some source of protein was in there, and I couldn't find it.  I was getting paranoid and uncomfortable, akin to that feeling of searching for your wallet at the checkout line, and finding it missing.  People were noticing me, but not gathering around, but I knew these people were looking at me.  Then I looked up, and saw Dan standing over me, Dr. 80's Dan.  He looked exactly like he does now, a little heavier, short hair.  He was holding a drink and looking mildly amused.  He was the only crystal clear face in my whole dream, and at that moment, I thought "this is a dream, I can't find this thing, and I have no idea why he is here."  So, I asked him.  There was some conversation, and I said something like "isn't fifteen years enough time to get over our bullshit?"  He was the only clear voice, too.  He helped me find the thing, calming me down and helping me sort through each section of my giant bag.  The girl in the room with me initially was off mingling and conducting this party.  There was a bar in the room, and she was behind it, serving drinks.  Everyone seemed cool and witty and urbane.  Dan was hanging out with me on the opposite side of the room, and he felt like the only person that really understood me in this room of "beautiful" people.  I was glad to see him, and I distinctly remember saying goodbye to him, before waking up.
