Follow up:
Night before last I had my second lucid , and I tried some object levitation.

I was watching TV with my family. We had just paused it and I went out into the kitchen and did an RC against the Kitchen Clock. After, I realised I was dreaming. My first thought was to run outside and start flying, but then I thought that my parents would be waiting for me to un-pause the TV (stupid me). So I went into another room, and telekinetically picked up a pencil. I used my usual two fingers, but did not touch the pencil; it took quite a bit of concentration. I then held the pencil in my left hand (along with a pack of others that had appeared) and tried to move it about a foot to the right into my other hand. It moved about half way, hovered a bit, then fell to the floor. I couldn’t concentrate hard enough. I then walked upstairs and decided to do another RC. Conveniently, an oversized, floating detergent bottle was nearby for me to read, however I don’t remember the text changing. I woke up after this.

I was happy that I'd had another lucid, but a little annoyed that I was still asleep enough to care about DCs.
