You said it was a totally lucid dream, yet you did not know you were dreaming. Thats kind of an oxymoron there. The definition of a lucid dream is the fact that you KNOW you are dreaming while dreaming.
yes sounds like you had an extremely VIVID yet not lucid dream. had it been lucid you wouldn't have thought it was real, you would have known it was a dream. however extremely vivid dreams like that are still a treat and don't happen all the time. I think the other difference, for me at least is when I do have a totally lucid dream when I wake up the memory of it is usually NOT as hazy as a normal dream.
