Meditation dreams

I had a dream where I was meditating and the buddha was present and he was helping me meditate. For some reason he seemed particularly concerned with the position of my eyebrows. I felt him guiding me into making certain facial expressions, which were related to certain states of mind. The buddha was vast, he was absolutely enourmous and powerful.

I had a dream where I was meditating and started saying the sound "ommmmm". It swelled to be like a divine sound, and it felt very loud like it was shaking the whole universe. It went on for a very long time, and I felt that it was causing profound change in the universe.
