When doing the exercise on tuesday, it felt a little strange because I actually did feel like I was moving through some sort of substance. I know that was the point of the exercise, but I guess it was one of the first times when I really convinced myself the substance/object was real. And sitting after doing the initial exercise felt funny...almost like I was floating or something. I don't think my body has ever been that relaxed! (I tend to be very tense...).
