That's not really going to happen if you haven't slept before, because you'll end up in a long period of deep sleep after the light sleep first.
MILD is something you might want to look into, it's a technique that has worked alot of times for me. You don't rely on dreamsigns or questioning reality, it's just like you increase your chances of getting lucid spontaneously.
You don't dream much in REM, so you were probably in it. Your cycles might be shorter than usual :) If you write down each time you wake up (and we all wake up after each cycle, it's just that we don't usually remember it), you'll see how long they are after a while.
Also, if you fall back asleep during the morning when you've already slept for a long time, you're in REM almost all the time. Barely any deep sleep at all. Which is why dreams during the morning can seem to last forever. The REM is just very long :)
