Try yelling freeze time in your dream.

Also, when you want a paticular dream that is pleasant. Try listening to ur CD which will help induce (or Incubate) a dream of your choice. Watch a movie before.

If you dont want to LD as often try a reverse technique such as RMILD which you say that you do not want to have a lucid dream and you will forget all of your dreams.

Congrats on being a natural, we could use yoru experience for our forum.

Stay...(usually at this point I say Lucid) but in ur case maybe you dont want to stay lucid.

Good Luck.
