I learned about the ability to do this was possible for me for a while. I always thought I was just doing something weird that held no real connection. But I recently realized that it was increasing my heart rate, making me breathless, and dilating my pupils all at once. I can also contract them at will.I thought that anyone could do it, just that they wouldn't. I also got the "superman" feeling. Whenever it happens I can use more force, but after-wards I feel slightly more tired than normal. Now I know what it is!View Thread
