Well, I’ve got many LD’s before i started be interested by LD. 10 days ago I’ve heard about that site. From those time, I had two full LD and one that i lost lucidicy (right ? =|). First was a week ago, and I got preety nice control (not fully). I tried to control weather(sucessfully) change my breath into a hurricane (succesfully) and fly (not succesfully =<). Few day later, I had a LD, and i was able to fly!. Unlucky, i lost lucidicy. Today I got really good LD, nearly like reaity. But then i got real problem: I was totally unable do fly , control weather, and do anything more than in real life.
Now i am asking You: Did anyone had problem with controling dream? How to beat it? Or even how to control? Am i doing anything wrong? Does exist any exercises that help to control dream? I was sure that when i know “I can fly” in dream i can do it. Now i am just confused. 
could that be the problem? you realised it looked like reality so your subconscious decided to use the normal waking life laws…
just remind yourself it is your dream and you can do anything
