Im new to the practice. I dont have a teacher that I can question. I practice following my breath in the tradition of Thich Nhat Hanh. I have been practicing for less than a year. One morning right after my sitting meditation I felt something in my head. It felt like something was unraveling and then a squirting occured. There was no pain but I froze when it happened because it was so unusual. I have since noticed a "shimmering" quality to my vision. Its as if there is more light but it shimmers- not rays. This shimmering is an all day thing. I havent found any information about this and I am wondering what it is, what it signifies, what importance it has if any. Is every meditators vision like this? Does it stay like this? What exactly causes it to be this way? Also objects seem to be more crisp in my field of vision.
its hard to find buddhists in the bible belt so any information will be much appreciated.
