My first lucid dream was like that, not sure if I was really lucid, or just having a dream that I was lucid.

I also had my first true lucid last night, didn't do any reality checks or anything, just knew and said the whole "clarity now" type of thing and rubbed my hands together (though that is as long as the dream lasted). Back to the point, I got the euphoric feeling, and I could tell that this lucid was so much more than the last.

I really don't want to bring you down but the way you are describing it makes me think of dreaming you were lucid (but what do I know, I've only had 1.5 lucid dreams )
