Shared dream

I had a LONG dream this morning for a 5 hour sleep which I was woken up from over 4 times, also cannot believe that I kept going back into the same dream each time I fell back asleep too, but most of it was repeated over and over because of this, so I am going to put the gist of it. In this dream, I revisited a place that I have dreamed of at least three times before in the past. The basic set up is a round store like building on a flattened area on the side of a mountain. The ground around it is flattened to have only dirt and is also shaped in a circle. There is a paved road leading down the mountain on the bottom side of the area and a dirt path leading steeply farther up the mountain that can lead to different places based on the happenings of the dream. This particular dream, it lead to another flattened area that held a round, huge, tent that housed a knowledgeable magical guy that looked like Clavicus Vile from the elder scrolls games. Skyrim to be specific, and without the dog. The main area was really just a through traffic spot, the majority I was always running up and down the highway at the bottom of the mountain at super human speeds, trying to find some kind of item for the magical guy. The other half of the dream I was talking to the magical guy himself. The part that sticks out most to me was the last part where I had to go to the final area and defeat the monster at the end. On the way there, I had to be ferried on a giant leaf by the magical guy himself. On the way there I would keep falling off the leaf and a giant fish would try to eat me and I would FREAK THE CRAP OUT! The dang fish looked like a miniature shark and I was so desperate to get back on the leaf I made the magical guy fall off, then we both struggled, then the leaf went under water. We finally procured a leaf and got to the stupid area. It was like a water dungeon, the walls and floor were made out of light gray stone. The first room had holes in the floor filled with water, and it had gray columns. The first run through I managed to defeat the monster, which was a hydra. The dream restarted back to where I had to be taken over the river to the dungeon about 4 times from waking up and falling back asleep. On the fourth time, I was in the first room when the hydras heads started popping out of the holes in the floor, the main head coming from the door to the next room. I started attacked him but my weapon was different, and I found it hard to use. It was the blades of chaos from God of War. Those suckers are harder to use then <PERSON> makes them look. I gave up and went back. I met up with the magical man and he told me he had fallen for me then went in and defeated the hydra for me, then proceeded to create a home for us in a room that was off to the side of the first room. I was flattered, but I was kind of just watching him do all this and was not really that into him. Then I woke up for good. That is the basic gist of it, I cannot remember all the specifics. I did this morning, but now time has gone by and I cannot. Should have typed it up when it was ripe in my mind, but I was busy, such a pity. Also, this dream was not lucid, and I am just wondering...how the heck did I see a multi headed hydra and not realized that that could not possibly exist in real life?!? Hope you enjoyed
