Thanks CanisLucidus, I appreciate that
I've reread many tutorials and watched many videos. That proved to be great! I found out about some little and big mistakes I've done, and I'm currently working to solve them.
The videos that were the most helpful were Tim Post's advanced lucid dreaming series, particularly the ones about meditation. They've been helpful because while Tim was talking about meditation, he didn't explained it in a "technical manner" so to speak but rather, he explained mediation from his point of view, and while doing that, explained his approach of lucid dreaming.
While I did watch the video when I was still a beginner. It didn't seem to have the same information I previously had taken, and it opened my eyes on something that I was rambling about all the time, but I wasn't doing it myself!
That thing is confidence in yourself rather than the technique and more importantly but very attached to the first concept:Try to take lucid dreaming on a more natural way. I noticed that while I knew that I have to put faith in myself, I unintentionally put it in the technique by thinking too hard about it and being serious more than I needed, and that backfired at me.
Another thing that I've noticed is that each time I get back to lucid dreaming, my lucid dreams number drops slightly. I found out -with the help of Tim's videos- that I was putting way too much effort and seriousness in my attempts, rather than taking lucid dreaming more "naturally".
Tim's explains this by mentioning that he had his first lucid dreamer even without knowing about techniques, dream recall. He had it by just being enthusiastic and confident.
I'm planning to get back to lucid dreaming "whenever I feel like it" because I'm sure that forcing myself to practice isn't going to help at all.
Here are the videos and Tim's web site, If you're interested
