Thanks for the input guys!

naikou,

I've been researching and practicing lucid dreaming for a few months now and I've had at least 15 or so successful lucid episodes with varying degrees of dream control. This was the first time I've experienced obstructions and distortions of this type within a lucid dream. I like your idea of looking at my feet. Will try that next time something like this happens! And yes, I've tried that spinning trick with a VERY high success rate. Not just spinning, but flailing, falling backwards, and rubbing my hands together (anything to feel my dream body move). Thanks for the tips!
