[HELP] A Very Strange Lucid Experience...

Yes, it does sound like you were lucid, but it also sounds like you had trouble staying lucid and keeping the dream clear. The fact that your breathing rates were the same is very realistic, as your real body and your dream body often share these traits, even to the point where the real body will be looking in the direction that your dream body is. I would suggest that you read this topic for more information on increasing and keeping lucidity.
