It's ok if you just remember fragments instead of entire blocks of events/dreams. Try not to rush out of bed so fast and see if you can remember any details. When you do, focus on them and try working backwards when events begin to unfold in your memory. That way you will recover more of your dreams. Also, if you already have a list of common dream signs, try going through them if you don't remember anything at all and ask yourself, is it possible that I dreamt about Dream sign 1? Then it might turn out that you did.

Keep up the day and night work. It may take a while for the practices to reach the subconscious mind, but eventually they will and you will find yourself lucid.
