It's quite annoying when you look back on your dreams and go "Oh, how didn't I see that I was dreaming" when it seems so obvious. I don't know how much having a dream journal has helped me but it can't hurt to have one and It's fun to look back on dreams sometimes. You might want to check out the pharmacy and read some of the topics(there's quite a lot, note: the pharmacy is in tutorials). I've had 3 lucid dreams so far(over like....a year or two)But I've never accomplished anything in them really. Either way, good luck in becoming lucid in your dreams.

I tink I went off topic.....=/
