Here is what I got so far:

My plan was to fly up the sky and eat a piece of cloud, then dive into the earth and swim to its core where the fire is and swim through there aswell, then go back and find water to walk on.. I became lucid late in the morning and I wasn't stable so I spun around and rubbed my hands, even came back to slightly waking up and tried again. After some tries I was stable enough and I jumped off of my balcony into the sky and flew around looking for a cloud, but the sky was clear blue (like usual in my LDs...) so I figured to just dive into the earth. I flew above a city so it was hard to find a spot that seemed okay, didn't take me long and I dove to the earth in one straight line and when I hit the ground I felt this sorta squeezing feeling and a buzz through my arms and fingertips. As if I had to squeeze myself into the earth. I couldn't see anything so I tried swimming but I didn't know if I was moving or not because I couldn't feel any dirt around me. It felt a little warm, but not really warm..like a blanket but it wasn't constricting me. I stopped the swimming motion and tried my flying style, like superman. This seemed to work because I could feel myself flowing through the ground. It felt a little different, like I was a worm and moved in curves. After a while I still couldn't see anything and I think I lost focus because I felt myself waking up real fast and I couldn't prevent it from happening so I woke up.
