I got lucid for the first time this morning

I was downstairs, thinking I still hadn't fallen asleep after going back to bed at 8:00 am.
It wasn't a False Awakening or anything, cause I didn't wake up in my dream, I was just standing there. Anyway, I went downstairs and some weird things happened. But then I suddenly saw my mom come home. knowing my mom is on a vacation in France atm, I said to my dad: wtf is mom doing here? to which he replied: she's not here...
At that point, I first thought I was hallucinating, and at that point I suddenly realized I had to be dreaming. I then pinched my nose, but I kept breathing, even when I tried to pinch harder. I then felt my heart nearly pounding out of my chest and realized I would wake up soon. I tried thinking about what to do to prevent losing this dream, but couldn't think of what it was >.>
So like most people, my first LD lasted for about 5 seconds ^.^
