What to visualise?

Hey,
I'm new to lucid dreaming and am in search of a method that works for me.
I read from several somewheres' that it's good to visualize what you want to dream about. As in you visualize the scene vividly, 'feel' yourself becoming lucid and experiancing said dream.
I would really like to try this out, but was wondering if there are better or worse things to visualize?
As in, to get a scene where you become lucid, should you visualize something crazy, to prompt yourself lucid, like a herd of elephants the size of mice being eaten by giant fish?
Or should you go for the calm scene, don't bother visualizing people, something easier for a beginner like myself. But all I've read about dreams needing plotlines or they are unstable suggest that it would be harder to stay lucid in one of these areas.
Which would be more affective?
Thanks, any other hints for a lucid beginner would be greatly appreciated :D

Oh, also...I've been trying to visualize the carpark of my school, because the only recent lucid dream I had was there. Is this a good idea? Or bad because I am often there and might just go 'okay, school...that's normal' and not be prompted to reality check?

What not to visualize?

I do not know what technique you are speaking of, but I guess it would work if you do it enough. I think you are talking about the second half of the MILD technique, where first you go to sleep, syaying to youself that you will wake up after ever dream and recall your dreams. Then, when youu wake up, you write your dreams down if you remember (and even if you don't remember) and then go to sleep doing the visualizing. Only in that technique you are visualizing that you are in one of your previous dreams and you realize you are in a dream in the dream... I don't know if that made sense. I will try to explain graphically:

You sleep---> Dream---> wake up and write down dreams--->visualize the following: [your previous dream(inside that dream you realize you are dreaming)]---> lucidity!!

Again, I don't knwo if how I am explaining makes sense or if I am just rambling.

Anyway, I am currently working on that technique right now, part of my improving dream recall plan.

How good is your recall?

I have pretty good dream recall, I've kept a dream journal for a few years already.
I tried this last night but...I just don't know how to visualize changing the dream. Last night I had a very fast paced dream that I was Bolt the dog fighting Cruella de Vil, and I was losing. I just didn't know how I could change that; I tried...but I didn't succeed anyway.
Thanks for the advice though

So you are talking about what to visualize afterwads when drifting off to sleep? I guess something that would make you realize you are dreming, like her telling you that this is only a dream or you finding some graffiti int he place you were fighting saying that you are dreaming. Then, you have to visualize what you would do if you became lucid.
