I have only ever anti-bended
I became lucid after noticing clocks, I was feeling unstable, and actually told myself in the dream if I stop stabilizing I'll wake up (as in immediately) this was a real problem because I remembered my highest priority goal, which was a behind the back hand summon. I found myself suddenly in a room with only a downward staircase and one door at the side. I began to descend the stairs, all the while rubbing my hands and bemoaning my lack of free hand for summon just then the staircase began to bend itself into a hamster wheel to trap me. It was about to cut off the only exit. So I had to un-bend it or be trapped. I forced the stairs back down but they appeared to go right into the floor, when I got to the bottom level with the floor, I noticed that the stairs didn't descend on thru but rather were corrugated. Descending stairs rubbing hands, being on bending stairs rubbing hands, walking across a corrugated floor while rubbing hands, this was quite the challenge. Finally I made it out the side door and thought I think I can hand summon now I'm stable enough I separated my hands and reached behind my back and instantly woke up DOH!
