I was Harry Potter. Yep, the same Harry Potter from books and movies. In fact, I looked like Daniel Radcliffe. Hermione and Ron Weasley were in the dream as well, as were several other characters, including teachers and others. Currently, me, Hermione and Ron were trying to find a hidden object. It turns out we had this really important object to find, and it was hidden somewhere in Hogwarts. It was kinda hard to find it, not because there were trials involved or anything like that - the problem was that it was hidden inside a really specific place, apparently a desk or something similar, and it could only be found by specifically checking out the place. It could be anywhere, and there was no way to locate it remotely.

To make things even harder, we were being chased by this teacher who wanted to stop us. I'm not really sure why she wanted to do it, but apparently some people thought we were doing something wrong. If we got caught, we wouldn't be able to find the object and somehow save the day in time. Ron had lagged behind us, so me and Hermione were running around and checking desks and shelves in rooms. We'd point our wands, yell "Wingardium Leviosa!" to make them levitate and then shake them on the air, thus dropping objects inside them, and checking under them as well. Apparently that was enough to find it. Me and Hermione ran through some stairways and into a room where we found three old desks in a corner. (Thinking now, the place wasn't quite like Hogwarts. It looked more... normal)

Hermione quickly waved her wand and said "Wingadrium Leviosa!". I waved mine to help her, but it seems I just got in the way, and we almost dropped the desks a few times. As I held the wand I could feel it producing an invisible force on the now levitating desk, and when it found resistance due to Hermione's movements or my on the wand would be pulled along slightly. We searched the desks in vain, and were about to head somewhere else when suddenly the teacher from before barged into the room, along with some other students. Me and Hermione moved to the back of the room. The place was quite crowded, but everyone seemed to stop on their tracks to watch what was going on. The teacher started to talk to us, trying to negotiate. Hermione carefully approached, but I knew she wouldn't give up. I held my wand, trying to conceal it on my back.

Then something happened - things were quite fast, so I'm not exactly sure about everything. Hermione moved her hand down and grabbed a wand - it wasn't hers -, throwing it across the room. She must have used some kind of spell, as it shot like an arrow and went somewhere among the crowd. I supposed Ron must have gotten it, but I wasn't sure. This didn't last more than a few seconds, so no one had time to react when she pointed her own wand at the teacher and shot a spell on her. I don't remember her saying anything, but a bright yellow explosion, with sparks, followed. The students were thrown back, and when we all looked at the teacher again we saw it - it wasn't the teacher. Hermione knew it - it was a vampire all along. It was a medium height strong man with dark spiky hair and dark eyes. He had a ferocious look, dark clothes and pointy teeth. He stared at Hermione with anger, and a dark aura seemed to move irregularly around him.

It was all his plan - he was pretending to be the teacher so he could stop us and attack Hogwarts. Still, even though he was discovered, we still were at danger. He was powerful enough to kill us all. All students backed away. Most weren't brave enough to do anything, so only me, Hermione and a few others could do anything while the teachers didn't show up. I pointed my wand at him... but I couldn't remember any spells! Not even Stupefy... Suddenly, a spell comes to mind, and I point my wand at him and yell "WINGARDIUM LEVIOSA!" Somehow, it works! I wave my wand and the vampire is thrown heavily on the ceiling, then with a second wave he flies through the door and out of the room. He wasn't beaten, though.

Hermione is shooting spells at him, as were others, but that didn't help. I decide I have to do something. I notice the door the vampire flew through was parallel to the one we entered through before. I run towards it. Hermione yells "Harry!", but I don't stop. I jump (somehow I'm quite nimble) and while still on the air I cross the doorway, point the wand at the vampire and yell again "WINGARDIUM LEVIOSA!". He was looking into the room through the other passage, so he didn't see me at first. Still, it didn't quite work: the spell seemed to shake him and somehow rebound. It was like an aura around him shook heavily, but I couldn't throw him this time. He slowly turned towards me, and I thought I was done for, when another of Hermione's spells distracted him. I crawl away and towards the room. Suddenly, another spell comes to mind, and I yell "EXPECTO PATRONUM!".

Somehow it didn't come quite right. The Patronum did appear, but it was on a corridor on the back. Still, I managed to control it. I ran back into the room and led it along the corridor, until it approached the vampire. He backed away from it, entering the main room again. It all made sense now: the Patronus' light would kill him! The vampire is standing in the middle of the room now, and I wave my wand. The Patronus runs and leaps in circles around him, when I flick my wand again and it crashes right into the vampire, which explodes in yellow light and sparks again, now disappearing for good. It took us a moment to make sure he was dead, but then everyone cheered. We were safe! Still, our commemorations didn't last long.

Teachers appeared. It seems the vampire and his friends had caused quite some bit of damage when they appeared, and it seems the matters were more important than we expected. We were taken to a balcony which showed a body of water. I'm not sure it was the middle of the ocean, but several large wooden boats were floating on the stormy waters and most of them were either partially sunken or were burning. They had been attacked. I point my wand at the water and yell "Aguamenti!". Instead of producing a stream of water I seem to create one out of sea water, which I use to put out the fires. Me and other teachers then proceed to leap out to them (again, abnormally nimble). We'd point our wands at them and yell "Reparo!" to fix them.

This went on for a while. We'd jump, fix the boats, then head to the next ones. Soon, the sea had calmed down, there was no rain and the sky seemed strange. We reach a platform which seemed to float over the water. I knew this place. I knew it was special. Behind us was the sea, but under us was a platform of floating stones which moved slightly beneath our feets as we walked and shifted our weights. Under them, it was... oblivion? I'm not sure, but it looked like space, the universe. I could see stars. The platforms circled a lava pit, which we crossed carefully, and on the other side changed color and style. Across the pit, a strange world existed: everything there was made of metal, and there were no organic creatures. Rather, the organic life there were the robots. Robots of all shapes and forms floated or walked around metal buildings and structures. A real robot land.

The sky here had another shade of blue, and when I looked back over the sea I could see it was different from our sky. Interestingly, the two skies met over the lava pit, which seemed to mark some kind of rift between realities. This wasn't another "place". This was another "reality". An elder, one of Hogwart's teachers spoke about it, though I seemed to know more than him. "I've seen this before", I said. "I saw it on that Lost videogame." I could remember somehow the main character from the game on a similar place (fake memory). "There are four worlds. One for each cardinal point. Our world is one of them, the Metal World [not sure about this name] is another, and there are other two." As I said this, I looked at the strange horizon, made of two matching skies which seemed to turn less real and be more ineffable as they got farther from their own realities, and wondered where were the other two words. I explained this place was where the worlds met. It was some kind of hub.

It seems the vampire's attack had taken some rather... epic proportions. We now were in need of allies from other realities to fix up things. We turned to the Metal World, where a small yellow robot flied around. The entrance only showed part of the world, as it did with our sea, and a somewhat small one, at that. It appears that the robots had built this as some kind of greeting area. Still, after the floating stones there was a large gap, and we couldn't cross it without permission. The small robot flew around and stared at us without interest. I'm not sure if someone spoke to him, but small balls of a gooey substance were shot out of the Metal World by robots, which landed and splashed on the empty space, forming small platforms. They didn't look safe at all, and I was worried about falling on the lava from the middle or - even worse - in the oblivion. Still, we carefully stepped on them and crossed to the Metal World. I wake up.
