welcome edmaster,

your lucky, iv been working on lucids for a while with nothing but thirty second lucid dreams,

One of my lucid dreams went something like this,

I am in a building i go to alot, and im looking out the window and every thing is dull, almost black and white, and then i just realize im dreaming without doing a RC, and everything gets really vivid and colorful and im like o yea, but then I got over excited and everything faded and went black.

so to answer your question, according to my experiances, yes it is possible

good luck and happy dreams
