Lucid Time!

These are dreams from some time ago, I cannot remember what days. But most of them are fairly boring, and I'm only putting them in for the purpose of my dream journal.

I was swimming in some harbor area, it was kind of half lake, half swimming pool, half lake with these huge concrete walls going up the sides. It was almost like a large cement dock for boats that was no longer used.
There was a small beach between the walls with a sandbar just big enough for two or three people to walk along. The harbor was quite wide though.
I met up with my dream guide and we went to go flying somewhere. (enter dream logic) We got onto some school locker doors and started flying on them like hover-boards. It was me, my dream guide, and this other dream character, a boy with black hair.
I commented on how it was strange that these people "looked so similar to people I've seen in dreams". In other words, I was very close to being lucid.
We flew on the locker doors out of the harbor area into a small town by the side of the ocean. We were flying very low, and weaving through the streets until we came to this very large square warehouse building.
The building was what I remember the most about the dream. It was made out of corrugated sheet metal. The sheet metal was supported by steel beams. The entire structure was very old, and had rusted and collapsed in some places. The floor was flooded, because the building was next to the water. There was a bridge stretching across the inside of the building, perhaps about three stories above the water.
Among some of the breaches in the building's side. vines were hanging, and the sunlight was showing in. The entire scene was very vivid, and oddly beautiful...
I got off my locker door and just watched. The male dream character flew down into some hidden door near the bottom of the building. My dream guide disappeared from the scene.

Once again, I was on some beach, but this was much more open, without the concrete walls. I was wearing only a swimsuit, and decided to go swimming.
I started to run in the water, just as a fairly large wave formed in the water. The sun was setting behind the wave, and I could see through it. I saw about half a dozen sea-urchin type creatures in the water. I began to run the other way, but the wave crashed and washed up to about my knee, and one of the urchin creatures was stuck into the back of my right leg, right around the back of my knee.
Once I was clear of the water, I noticed people running from the water while screaming. Some people had as many as ten of the urchins stuck to them.
I looked at the one stuck to my leg. It was about the size of a fist, with spikes about two inches long. And this was the weird part, the urchin was actually a bright pink color.
But the spikes were stuck in my legs and there was blood pouring down. I bent over and puts some sand into the palm of my hand. I used my hand to knock the creature off my leg without touching the spikes directly. But I could feel the stinging sensation spreading, as though I had been poisoned.
The last thing I remember was some dream character, a boy with black hair pointed a gun at me. He didn't have any of the creatures stuck to him.

I was talking with a group of people online via Skype chat. Everyone I was talking to was from this website (Dreamviews) and we were moderating the forums.
Our goal was to find people who posted fake dream journal entries and pretended to be really good lucid dreamers when in reality, they were not. We were supposed to take down the fake DJ entries.
Somebody accused me of being one of the fakers.
