I was wondering, I have been drawn to the tigers eye for many years. I put a bowl full of tigers eye in the sun today on a windowsill and since the sun went down, I have been toying with one, since I started doing that I have a strange sensation in the middle of my chest, this has never happened before and when I put the crystal down the feeling goes away. I feel almost breathless and like I am expecting something. I want to know if this is normal and what it could mean. Please someone help. Thanks
