I found this site yesterday and read about the importance of a dream journal to write everything you dream.

I went to sleep trying to keep in my mind the idea "I will know when the dream start". But know way... I had a nice dream but my mind didn´t remember me "Hey, you are in a dream...". Anyway in the dream I saw John Locke from Lost wich may be a good signal... hehehehe

So this is my first dream in my journal and I hope that soon I will achieve my first LD. Faith may be important too, isn´t it?
