false awakening

The first thing I remember about my dream was that my best friend and I were in this huge canyon in this river. The water was really murky. I looked over at her and I shouted to warn her that two crocodiles were surrounding her. They were not moving at that point, but once I warned her, they started thrashing. So I swam onto the closest shore while my friends swam across the river to the other side. There was barely any shore though becuase at the edge of the waterliine was the wall of the canyon. So, I tried to climb it to get away from the crocodiles which later turned into sharks. I escaped, but I forgot to check if my friend did too! I then was in this weird city looking thing, but it reminded me of a videogame because I had a quest and there was a little arrow in the air pointing to my destination. My quest was to find my brother's book before he does...so I go looking for it, but the arrow disappears, so I'm all alone. The city then turns into Barnes&Noble and I'm frantically looking for this book. For some reason, I then change my mind to want to find a Hunger Games book and I did Barnes&Noble then turns into this school with a bunch of kids in it, and I felt like I was inside of this really corny movie about I guess Middle School romance? I have no idea.... But there were a bunch of love triangles and fights and then at the end almost everyone made up.. I have no idea why I dreamt that. The end of that scene took place in a courtyard outside. Across the courtyard I see the most beautiful modern day castle I have every seen! It was huge, and i told my friend that I would love to live in one of the really high towers. I then realized my brother works there... I go inside and my best friend was there! I looked into the doorway and my best friend's uncle (in the dream) was chained up to be beheaded... Then he mysteriously came back to life and told us that we were going to do great in life.I appeared in my room at this point. I remember looking at this card with a saying on it that said something like "The vampire that looks at this will be dreaming." or something like that. And then I remember questioning reality and doing the nose-plug RC and being able to breathe!!! (Btw, I've read other DJs where people say that they love doing the nose-plug check becuase the sensation of breathing while plugging your nose is really cool. I never understood that until last night. It was pretty cool) But the thing with this lucid dream was that I thought I had been awake and that by my reading the card I had fallen asleep! So my lucid dream within a non-lucid dream felt REALLY unstable and I remember vividness was TERRIBLE! I kept rubbing my hand, but nothing worked! I summoned a door in my window but it kept leading outside; I didn't want to jump out the window. I could tell I wasn't very aware of things because there was a huge flagpole outside my window that is not there in RC and if I was truly aware, I would know that I could just jump out. I turned around and tried summoning another door to a beach, but "woke up" standing in the middle of my room. I did a reality check, but I couldn't breathe through my nose! So, I reread the card and the reality check worked! But the dream was even worse than before, and I "woke up" standing in my room again. It was really annoying because my main dream, or the non lucid part was really stable and clear! But just because I thought I fell asleep in my dream, it made it really foggy.
