Thank you CanisLucidus for your response!, I had a bussy week and couldn't put much effort on my DJ and my concious attempts to LD, but I finally had some time to come back to the forum and hopefully getting back on track .

Last week I tried three times to WBTB after maybe my 4th sleep cycle, one of those I fell asleep and the other two I could't do it, I mean I reached the stage when your body is kind of sleeping (not SP, I dont know if it has a name), but could't go thorugh all the nREM stages, my mind was fully awake for about an hour until I gave up, change position and fell asleep after a few minutes. I don't know why, maybe I was trying to hard, or it was because I did it lying on my back when I usually sleep on my side. Or maybe I was just doing it all wrong!, I mean in other moments of my life I've got to that moment when your mind kind of switches to the process of sleeping and even had hypnagogic imagery and everything you should go through, but this time when I was trying to do it on purpose, I just couldn't get there. Does anybody has any advice on this?

Anyway, the last night that I unsuccessfully attempted WBTB I ended up having a short LD. I woke up a few minutes after I fell asleep (I guess), during SP, and immediately saw the opportunity to LD, so I ignored the "pain", closed my eyes and waited until a dream was formed, and a few seconds after I was inside a dream. I didn't think on doing a RC as I was sure that I was dreaming, I screamed "lucidity now" to stabilize the dream but it didn't work (though I saw the horizon shaking a little), so I tried to reach the only construction that appeared on the scene to find something to touch and explore how LDing felt like. I passed by some inoffensive DC but halfway there a group of nuns appeared and for some reason started throwing nuts to me (with shell), at first I though I could just "decide" that it would hurt me, but when I felt them hitting me I urged myself to reach the building to scape, as they where getting closer to me. Sadly, they finally reached me and I woke up. Is it normal that DC are so aggressive? In my first parcial lucid I was also attacked by DCs, I could certainly fly and get rid of them, but apparently during a dream it isn't the first thing that comes into my mind.
