This was the weirdest thing ever. [MILD + RC fail ?]

As the title says, it is the weirdest thing I have experienced. Yet, I haven't had a Lucid Dream :(, but I'm not giving up!
So here's what I experienced yesterday:

I had to complete a science project and I slept late..
When I went to bed, I told myself :
"Tomorrow, I will remember my Lucid Dream.
You know why ? Because I WILL Lucid Dream."

Then I began sleeping.
I'm now in a Dream. The dream was really, really vivid. One of my most vivid. Guess what I was doing in the dream ? Reality Checks. Billions of reality checks. I was plugging my nose while talking to friends, running everywhere while doing Reality Checks.. It was really weird because I could feel myself in the dream body but not completely controlling the situation. :shock: It's like I was doing Reality Checks like a habbit, without knowing their meanings.. :?

Any thoughts of what happened and how could I have been Lucid that night ?
Is this a good sign of my progression ?

Thank you for your time and of course, sweet dreams :shadewink:
