I recently became interested in the method of loci (http://en.wikipedia.org/wiki/Method_of_loci) technique for improving memory. I was wondering how this could be affected by lucid dreaming, i.e. one could visit their "memory palace" and perhaps reinforce the memories or place items there to be recalled later.
Since I have yet to have a lucid dream, I have been unable to try this out, but I figured that someone here might be familiar with the memory technique, and may want to explore this idea further.
