Well I'm much older than you guys but I started around your age.  I was recalling vividly 4 or 5 dreams with lots of details spending a ton of time writing them down by hand in my dream journal.  It took a few months and daily practice but I still remember my first lucid awakening like it was yesterday.  I had never experienced such vivid details and colors in my entire life.  It completely changed my worldview.

One great trick is drinking a big glass of water before you go to sleep.  This will wake you up in,a little while giving you a great chance to recall you dream, record it, and then go back in for more.  Sometimes I'd repeat the process and spend all night having new dreams this way.  Make sure it's water and nothing else.
