second the bok recommendation. and it sounds like you are well on your way. the on the fly book authorship should be a valuable dreamsign.

one of my clearest, strangest lucids was one where i realized i was dreaming while reading a book at the kitchen table. everything was stable, except the words were repelled by my focused vision, and always darting about so that the most i could catch were "the's" and "ands"

good luck and happy dreaming..
