awakening in the early morning seeing white sky and wood patterns slowly departing like falling from a great height into

At the hour of Yin, I opened my eyes and saw a white sky, with patterns of wood grain slowly drifting away from me, as if falling from a great height, as if slowly descending into the abyss, there were people in blue and white clothing talking to me, but I couldn't hear them clearly, then I continued to fall. Suddenly, there were gray shadows talking to me, but I couldn't see or hear them clearly.
