Lucid Dreaming? why now?

[StarlightNight]

Hi, I experienced 2 dreams so far in about 1 year and a half in which I suddenly was aware that I was dreaming. - The first one I was in the middle of a crossroad speaking with two other people a man and a female I didn't recognized, in what looked like a shopping mall or a train station. Suddenly I said the the man something like, ''I have no time to speak to you right now, I am currently dreaming and might wake up at any moment''. That was bizzar, afterward I ''left'' the place and a nonsens dreaming took place. - The second was between two dreams sort of, I was in what looked approximatively like an outdoor marketplace with restaurants. I suddenly became aware and said to myself ''I am Dreaming!'' all became vivid and very clear I could see in minute details and control my movements at will. I went toward at the checkout in some sort of restaurant and looked up to the waitress right in the eyes but the awareness dissolved little by littles and the rest of the dream was no more lucid. What does it all mean? I didn't even konw this kind of dream had a name before researching about it. I started experiencing them as an adult, never before can I remember doing so. I practice self-awareness meditation for 20 minutes each day for months now to calm my anxieties in life, could it be a cause? Thanks.
