It's really exciting that you got to build your own dream mask, trying to find the design that's best for your own needs. I have to agree on some of these masks looking quite uncomfortable. I can't even put a normal mask most of the time because it gets entagled with my hair and also like to sleep sideways. I wish you all the best with your project, sooner or later you will find a way to set those lights right and they will cue you about the dream state.
Even without the mask, your progress is really impressive. Like you said, just 10 lds, but it seems to me that you have already 50 or so. Long lds, great recall, totms completed. Oh, congrats on the latest Totm by the way. :goodjob: As I was saying to Steph, I am truly impressed by people who manage the counting task. Some of us here don't even dare trying it. :P
I guess if you catch your lucid among a number of other dreams, the amount of self-control or straight forward thinking would be a bit less than if you catch it among the first dreams after a wake- sleep moment, like wbtb or natural wakes (but then there might be other difficulties with these). Sometimes the dream scenarios can be really overpowering, that's why it helps to have the task ready beforehand. I like a quick Q&A session with myself during the day or just the mantra before bedtime or wbtb. Q&A: if this was a dream, what would I do A: task (one two words), or the mantra "I realize that I am dreaming, China Wall". I like to keep them short and simple, but whatever sounds good to you. You may add some sort of mental word rhythm as you pronounce the mantra, I've heard it helps.
Finally, your recall seems fine, so I wouldn't worry about it too much at this point. If there's some persistent disturbance then we may think about it but it's better not to have your subcon on a negative mantra like my recall's not good. Your recall is great!
