I've been trying to get lucid during dreams but most of the times it doesnt work for me

sometimes I get like sub lucid (if that is a word hehe) I mean I dont fully realize that I'm dreaming but I do know how to bend the rules.
Does anyone of you guys know
Waking Life?
Its a really interesting philosophical animation movie about lucid dreaming, like reality is one big dream.
When I'm going to sleep I always notice a few states of sleep:
first stage: my body gets very relaxed
second stage: where my thaughts get intenser, increased thaughts visualisation
third stage: logical thaughts patterns seems to get distorted and one thaught can flow into another thaught wich has nothing to do with the first one
fourth stage: leaving the waking world and entering the dream world, now I'm really starting to dream. and because of the thaughts overflow in my mind I cant seem to concentrade on the fact that I wanted to have a lucid dream in the first place
Here are a few tips for those who want to experience a lucid dream:
In your waking life try to add a few extra things to your daily life, like when you see a light switch turn it on or off and see if the light goes on or off, but really look at the light and ask yourself if the light really went on or off.
In a dream you cant usally adjust light levels, so if you get this "light switch action" in your thaughts system you may want to try it during a dream and then realize that you are dreaming and become lucid.
I got this tip from the movie Waking Life by the way.
Another tip is to watch a digital or analog clock, if the display seems to be all screwed up or there are to much or to less numbers you are probably dreaming, also try counting your fingers (lol that sounds stupid).
And last but not least, from the Waking Life movie this guy said that small patterns such as ae. a clothing trade mark logo are very unstable and can change very often.
But anyway I'm going to sleep now hehe I'm pretty tired, hopefully I'll have a lucid dream tonight. Wish me luck
