Thanks a lot everyone!!!! Here are some things I'd like to point out:

- I haven't actually slept well in the past few months. I wake up several times during the night, and have a lot of trouble getting to sleep again. I don't know why this happens, but it's screwing up my sleep pattern and even my waking life. I'm seeing a doctor soon to try and find out why this is happening. That is too, I think, why I can't WILD. If I wake up, I have a lot of trouble getting to sleep again, so whenever I try wild, I just lay there for hours fully awaken, thus not having the opportunity to let my body fall asleep while I'm aware of it.

- MasterMind, that was a very insightful post. I already read somewhere that if you wake up from a dream, and go back straight into a DEILD, it gets more vivid, and that's pretty interesting, because the less I have to "wake up", the easier it is to me to sleep, for the reason I mentioned above. So if I try it, the worst case cenario for me is just falling into regular sleep. Thanks for reminding me about that. But is there any way to intentionally wake myself up from a lucid dream? What about a non lucid?
What I'm trying to do is setting a custom alarm at 7am, as CrazyInsane's tutorial says, but it's not working so far cause I'm setting it too low, and it doesn't wake me up. I'm still trying to find the right volume, that will wake me up without startling me.

- And about the main subject in this thread, vividness: I'll try to combine the "clarity now" method along with the "surroundings awareness" method and see if it gets more detailed and vivid. Those were some real nice advices, thank you. And now that you mention REM dreams, I just noticed tonight that the last dream I had (around 8:30am) was kinda vivid. I dreamed I was in an airplane with some local football players, and the color of the sky were very bright, and when I had a beer with one of them (lol) I could even feel the flavor of it.

- And last, since I'm depending so much in DILDs, at least for now, do you guys have any tips aside from RCs and DJ to have LD's more regularly? I say that because all my DILDs seem to happen at complete random, and I'd like to increase my number of dreams so I can practice more, at least for now, while I'm fixing my sleep pattern.

Thanks again.
