First medium-high level LD

Well, I've been trying to LD for a couple months now, and so far I had only low level lucidity, but I finally had a lucid dream last night where I felt pretty much in control, thought I'd share it.
I don't know exactly how it started, it was at the end of some dream where I got hit by a missile or whatever, and everything sort of faded to white, then I appeared next to my school and knew I was dreaming, RCing to make sure. Some guy was with me, so I just decided to walk down to the school with him and see what happens. Before going down, I tried jumping to see how high I would get, and floated above some car for a couple seconds. I went back down and looked around and there was a huge crowd in front of the doors, and I pushed through them to try to get in the school. At some point I wanted to just try walking through the doors to see if it would work, but as I started walking through one a friend of mine in the dream called me, and I lost focus or something and sort of got pushed back out of the door. I got in the school and a couple of friends were asking me if I wanted to go up to some store with them. I thought about it for a second, and thinking that I should just try to go with the flow and not change the dream too much for fear of losing stability, I agreed. When we went back out through the doors, I tried going through it directly again, and this time it worked, I pretty much floated through it. Some friend was watching me though and looked sorta freaked out, and funnily said something like: "It's kinda weird when there's a ton of people around, it seems like people are just floating through the doors..." At this point, I'm not really sure what happened, but a timer appeared in my vision at 54 seconds, and starting going down. At around 20 seconds, I think I totally lost control of the dream, and a bunch of weird stuff happened that I can't really remember. I woke up into an FA, thinking about the dream. The table next to my bed was covered with a bunch of pills, and a piece of glass was on the floor. I picked it up and tried to attach it to the table, but it just fell back down.
That's about it, if anyone has any comments or maybe an idea of what the whole timer thing was about, I'd like to hear them.

Gratz on the kewl LD. The reason I think you visualised the clock was because you believed that your dream had a time limit to it, as I sometimes do. I get into a state thinking, wow this has gone on for a while, and my mind is wondering how long left I will be in this state. Just my opinion,
