Finally, my first LD and a question

hey guys

after trying to become lucid for about 3 weeks. I finally get my first LD.

well, it actually came quite unexpected. i was dreaming that i was in a ship's cabin then someone came in and told me that we encountered a storm and the ship is going to sink. i then quickly went to the door to the deck but found it stuck. suddenly i knew i am dreaming.
i then opened the door and went into the deck. i was surprised at the feeling of the storm. it just like in the real world!!!! i tried many things, including detonating a bomb and found myself blown into the air:D.

some questions

I found that the surrounding will change by itself, It happened so naturally that I can hardly detect it. How did you guys overcame this?

Really, your dream is going to have sudden changes. I mean it's not set in stone like the real world, it is just a dream so some things are going to change. And you said you could hardly detect it so I mean is it really bothering you THAT much?

The dream world changes constantly in large and small ways based on your unconscious associations and emotions. I suggest reading the tutorial on dream control here. It explains it all really well.
