I did a 15 minute focal meditation today. I decided to put my half full glass of water on my small table and placed it in front of my eyes as I sit in my usual spot and position. I proceeded with the breathing and mind-clearing exercises, and began to focus solely on the water in the glass. It was actually pretty difficult, because I had no lights on in my room, and it was nearly dusk. It got to the point, where I could only see the water and a faint outline of the glass, and the water turned into a subtle rainbow of color. Then I heard some classical music playing, but it was extremely distorted and almost alien-like. Besides that, nothing really interesting happened to the time where I ended the meditation.
