Yes I believe many people call this dé-ja-vu. There is a topic about this in the Beyond lucid dreaming forum. The BIG Déjà Vu topic
Personally I am trying WILD as my main technique, but I also do certain things during the day to try to cause an RC induced lucid dream. Whenever I find the environment feels dreamy, I have trained myself to do an RC. I also do RCs when things don’t work as expected.
With the WILD attempts I basically relax and clear my mind of thoughts, I have tried to visualize things too and this worked quite well. Eventually I find thoughts form that seem much more random than normal and the images are extremely vivid, I believe this to be HI. From that point I am working on entering the dream and becoming part of the dream. Mainly by imagining myself as part of the scene, usually as somebody stood watching the scene.
