I have done a search on the word 'cheese' in the threads and was suprised to find that only two instances of the word occuring. I can almost guarantee that if I have cheese before sleeping I will have a LD. I find that strong cheese is best and as I love Stilton, St.Agur etc, I have extremely vivid and lucid dreams.
I can remember one occasion where I spent the entire dream going around the environment I was in testing everything for texture, smell and weight. It was all absolutely the same as real life.
Try it, it may work for you too.
