I agree with the previous posters. Also, I think we should be happier that we get lucid during REM, because then we can control our dream, and we have a better way of relieving our stress (or at least for me personally). As what Matte said, I would also much rather prefer waking up feeling giddy over having been lucid than getting a few extra minutes of sleep...unless of course those extra minutes are spent lucid too! Haha
