I entered a hallway with high ceilings and dark wood paneling. Weary and in a hypnogogic daze, I realized a series of white marble statues lining the hall, each maybe 3 feet tall placed upon 6 food columns. It was after realizing the visuals that I then heard the idols producing a most eerie sound. I noticed they all had pursed lips and the sounds was like whistling; but not as sharp sounding as normal whistling. It was a loose choir, slightly cacophonous, droning slowly and softly. This "music" made me collapse once I had a grasp of it and I crumpled there in the middle of the hallway. I was having a vivid dream within a vivid dream. My body was no longer constrained by gravity and I was pushed into the main chamber at the end of the hallway as though I was pushed by a wave of water. I knew that I was dreaming and was not afraid when I realized there was an large entity in the large chamber I entered. It was not a visually well defined entity. It was 30 ft tall, roughly humanoid form, but its body was covered by planks of dark material. It was almost like if it were hair covered but each hair fiber had grown planar and monstrously large. I went through a few bouts of flying up and being smashed into the cobble stone floor. I was able to raise myself 3 or 4 times before I was forced to the floor again. Then I lost consciousness and awoke from the dream within the dream. The dream continued on with some wierd stuff (james, tim and pete were in a rock band playing a house party, mark h was making out with my childhood neighbor), but the 2nd level dream was so real and weird. I woke up later feeling like I had really been gasping and sputtering with the flight and bashing.
