Reality Checks failed

[starfox69]

This morning I was feeling kinda sleepy so i thought "why not take a nap and try and lucid dream" I was really excited because I just had this weird feeling that I was finally going to become lucid, but ALL of my reality checks failed me, the dream went down something like this: I had a false awakening and got out of bed to get a drink of water, as I walked to my bathroom I noticed a water fountain in the hallway and I thought "wow that really useful" so I started drinking from it. At once I realized that I didn't have a water fountain in my house and form some reason my first conclusion was that I was hallucinating, but I could feel the water in my mouth so there was no way it was a hallucination. Then I realized I may be dreaming so I sprinted back to my room to look at my clock, and crystal clear even with the right font and everything it said 2:30 PM (I feel alseep around 9:30 so there's no way it could have been 2:30 but I wouldn't really expect to notice that in a dream). Since my clock worked fine I tried the nose pinch, no matter how hard I tried I couldn't breath so I thought damn maybe I am awake (forgetting about the fucking fountain in my hallway). Feeling defeated I walked back into my bathroom, my reflection looked completely normal in the mirror so I was almost convinced I was awake but when I went to turn on the light they wouldn't go on (one of the switches is also connected to a fan witch didn't turn on either) and I thought "HOLY SHIT I AM DREAMING" Just to be sure I raced back to my room and tried the lights in there... they turned on with no problem so I walked back into the hallway, staring at this water fountain think "I know that I don't have a fucking water fountain but 4 reality checks just told me I'm awake what the fuck is going on?" I don't quite remember what happens after that but I woke up shortly. Can someone please explain to me how in a dream I had for the sole intention of become lucid 4 reality checks all told me I was awake?
