Hi, a few days ago i was talking to a friend who told me all about lucid dreaming and after a few google searches i found this site I've been stressed out from my yearly exams but I've got 2 weeks of holidays coming up so i hope to get some good practice in for lucid dreaming

I have a few questions..
I've only just started trying to lucid dream, how long does it take the average person to have their first lucid dream that they can recall?

also i find it very hard to remember my dreams, most of the time i can remember at least one but sometimes from what i can remember nothing out of the ordinary happens... like one of my recent ones i was just sitting on some grass talking to friends, are these dreams still worth writing down? I didn't because it was 4am
