I never was able to take on lucid dreaming, I'm not sure whether it was a lack of motivation or I just never got around to it. But last summer I spent 2 weeks in Canada, and every night before bed we would do Yoga for 30 minutes, and then a Yoga instructor would guide us through a trance that lasted about 15 minutes. Only 2 or 3 out of 10 of us were actually able to do it effectively, me being one of them. Now every once in a while I lay down in corpse pose and spend about 2 hours in my trance world thing (which is really between 15-30 minutes, but when your in a trance time feels different to you, so it's like 2 hours). Of course, you have to know how to do it properly or you could damage yourself physically and mentally. As lucid knows, I was abruptly woken up in the middle of one and became very sick. I couldn't leave my bed for 3 days.
Sorry about being so off-topic, but I felt it kinda fit in. I'd like to get a start on lucid dreaming, it sounds like a fun experience. If I remember correctly, one of the first steps is to do something repeatedly (like look at your hands or a digital clock) throughout the day, and then you will start to notice the action happen in dreams, right?
BTW where even did the original topic go?
