What are Some Stress and Anxiety Symptoms?

I know most of them but i wanna know more about it. One of them is a wierd noise in your head am i correct. I get sudden bad tastes in my mouth. And when i yawn my ears crackle. and sometimes my ears pop when i chew and i have the keep chewing to try to un pop them. I get a cold rush go down my legs when i get nervous. And i often think of things that would never happen. I have been having bizarre and wierd dreams. And that feeling that someones squeezing your heart. And now tension headaches ever day and it feels like a rubber band is around my head.
