I think I actually did this over the weekend, unbeknownst to me. I started flying in a dream I was having at the instant I started to fly I knew I was dreaming. These are my favorite kind of dreams so I decided to make the most of it. I launched myself straight up into the air, much like you advise CFT. But instead of finding an astral environment, I found myself looking out over the Dallas, Tx landscape. Everything thing seemed super real, like the wind and the clouds. Maybe I projected into the RTZ? Or maybe I was just having a very Lucid dream
