okay so last night I was having a dream about me surfing on some wave (I’ve had a lot of beach dreams lately) and I became lucid, but it was an extremely dull and black lucidity, so I shouted “lucidity, increase!” (I read about it on another post) and nothing happened, and I woke about a second later.
what other terms do you use to increase lucidity that work?
thanks 
You can say:
Increase lucidity now!
Lucidity times 1000!
ETC.
You can say anything, ANYTHING, you want so long as you believe that it will do what you want it to. If you made up a word and attached your absolute belief that this or that will happen when you say it, then it will. So long as you have doubt, will a method might not work. Try yelling it repeatedly. I had one LD where I realized I was dreaming in a field. I said lucidity times 1000 and nothing happened. I yelled it three more times to the wind with all my might, and sure enough, everything snapped into ultra-sharp vivid focus.
In short, you have to believe to achieve… 
that’s very true!
I think if I had stayed lucid longer and said it a few more times it would have worked, the problem was that I woke up so fast 
thanks for the pointers!
A good one that i read of is: Paying attention to details on things. Like if you became lucid in a classroom, pick up a pencil or eraser or any other object and closely examine it and pay attention to how it feels in your hand the details on it and that increases the visual. and to increase the audio pay attention to fain sounds in the background. closely listen to conversations people are having untill you feel more embedded in the dream. Just do that with all the senses
I used this method once and it worked, but later I figured that this didn’t helped me to gain more lucidity but to get more power, because I needed instant power, but maybe that is related, maybe more power <=> more lucidity…
And like Dreamscape_Awakener said it helps if you pay attention on something once you’re lucid either smell, touch, voice or anything else, it’s important to stimulate some feeling and pay attention to them, and you can use spinning technique or rub your hands, but I believe that you heard about those…
Peace!
That’s how I increased my lucidity once.
At another time I focused really hard on looking at one object (which was the moon), everything else disappeared but the moon, so I commanded my dream to reform everything else.
some people say you can take a lucid pill 
i haven’t had the chance to try this out yet. but it always reminds me of the Matrix 
Calm, practice and experience…
