I know this is about the billionth first lucid topic, but this is different because it's my first lucid

So anyways, this morning I woke up really early, around 5-5:30, got up to pee and then went back to bed (ok, you probably didn't really need to know that). Anyways as I was falling back to sleep, I kept thinking to myself "I WILL have a lucid dream, I WILL do a reality check" over and over and then in my dream, I was standing near the entrance to the toilets in a place I know well and this woman who I know went into the men's toilet and I thought "huh?" so I tried to open the door and it wouldn't budge. Then I thought something like, "hmmm..." and did a reality check (holding my nose to see if I could still breathe) and realised I was dreaming! I couldn't move for a few seconds and I was trying to decide what I'd do, but then I started floating backwards and everything went blurry and I woke up - must have been because I was so excited, but yeh... YAY!

Anyways I'm looking forward to my next one... It's weird though, after I woke up I went back to sleep and had a completely ridiculous dream and it didn't even occur to me that I could have been dreaming ... It's pretty amazing how realistic it was, though... For that few seconds, anyway... So yeh

EDIT: forgot to mention, I started trying a few weeks ago, then sorta half gave up for a while but then this morning I tried again and it worked ... I had been browsing these message boards last night, though, and I read something about telling yourself stuff like "I will have a lucid dream tonight, I will do a reality check" and stuff and how you have to believe it and it worked for me... At least that time it did anyways...
