Him

I had a LD that lasted 2 full rem cycles and I only exited the dream once at the end and used wbtb to re enter it. It's to long to explain everything that happened but here was the gist of it.

I woke up from a non lucid and used wbtb to enter a dream. I was in a subway station and found a version of myself but I made myself invisable. I spent the whole dream following myself around leaving things that would make my life better (spawning money and leaving it on the ground). I followed myself doing a ton of stuff. I met a few dreamers who were doing the same thing and joined them in following them around helping their "awake" versions out. In the dream, I went on about 3 train rides, a shift at work and a class. Midway through, I was pulled into the sky and woke up. I opened my eyes, glanced at the clock and fell back asleep immediately. I re entered the dream and continued for a whole other rem cycle. The last dream ended with a flying match of paintball.

There was another brief LD I could move short distances at the speed of light.
