SUCCESS! Finally had my first successful dream just barely using the FILD method.
I tried a new reality check today. Plugging my nose and trying to breathe in through my nose. After moving my fingers back and forth for about 2 minutes I felt this tingling sensation all over my body. I tried my reality check and found that I could breathe through my nose even though it was plugged. I was still laying face down in my bed with my eyes closed at this point.
First thing I had to do was lift myself away from my body. I took this very slow this time since last time I woke up at this point. I tried to lift myself away and open my eyes and I saw black fuzziness and heard a dark laughing voice. I got rid of that in my head and kept my eyes closed and slowly sat up in my bed and thought to myself and imagined what my room looked like. When I opened my eyes, I saw my bedroom just how it normally was and then my dream took off from there.
I can't remember much but I think I stayed in my room for a bit just walking around looking at things. I remember trying the light switch and it wasn't working properly thus indicating again that I was in a dream. Finally I ran for my window and jumped outside and flew straight up into the air spinning as fast as I could and finally when I stopped spinning, I fell down into water.
I was actually swimming inside of our fish tank in my basement. I kept doing my reality check to make sure I wasn't going to drown and sure enough i could breathe underwater. I swam around for a while and decided that I wanted to break out of this tank. So I imagined it in my head and started swimming faster and faster until I reached such a high speed that when I rammed into the acrylic of the tank, it shattered open and I flew through to my freedom.
Outside of the tank I imagined me being upstairs outside my room and my bedroom was full of water spilling out everywhere. I couldn't breathe at this point so I laid down and took a breath of the water that was spilling everywhere. I can't remember much of what happened after this point. I just remember seeing a cute girl and we just walked and talked in a very dark setting and sat down on a bench. I don't know if I asked her about myself (which is one of the things I want to be able to do) but after talking to her, I think I woke up because that's the very last thing I remember.
Feels very good to have a decently good lucid dream and all of the reading up on things about taking it slow and spinning to change the scene definitely helped keep me lucid for longer than I expected.
