I had my first lucid dream in a while last night, and although it was very short I still managed to (sort of) do the first task!

I was on a train, and there was all sorts of laundry around. I was looking for a pair of socks, because for some reason I was barefoot. Then I realized, "why is there laundry on a train?" and realized I was dreaming. At the same moment, I remembered the challenge, and quickly looked around for any people. The compartment was completely empty, except three or four people at the very back. I quickly went over, but they were just sacks of old empty clothes and not really people, so I said "Have a head," and heads appeared on them and they were real people Then I asked, "Are any of you lucid dreamers too?" and two of them said they were. I asked them where they were from. The girl said "Haikiki" (possibly thinking of Waikiki ) and the guy said Iowa. Just then I saw the socks I was looking for and got distracted, and went on with the dream. It was kind of fun

So I know it wasn't exactly a crowd of people, but maybe I've got it anyway?
