I never focused on anything. I keep my eyes shut and imagine myself floating. Sometimes I find myself trying to break SP ( which is the most uncomfortable feeling to me ) but I try to continue to relax. Once I project my sensations to floating then I just mostly relax and listen to all the strange noises. I also focuse alot on my breathing well I can't help but focuse on it because it's all funny sounding and strange. After what feels like forever I open my dream eyes and I find myself in my room on the floor maybe 95% of the time. From that moment I'm Lucid and I'll usually walk through the wall so I can go outside and have some fun.
