I'm sure you have all heard the old adage, "If a tree falls in a forest, does it make a noise?" Well no, it doesn't. When a tree falls, it sets-up a vibratory pattern Without the ear of a human or another animal to pick-up the vibration, it doesn't make a noise. Even with the ear, it still doesn't make a noise if a brain isn't there to interpret the vibration.
So when you stub your toe, the reason you know that you did is because your brain/mind will interpret that you did.
Now, to get to anxiety, and cutting out the middle man... Most often, our mind will determine a sensation from our body, be it pain, itching, what-have-you. But the mind doesn't need the body's sensations to create the feeling. It can create all sensations all by itself, without anything going on with the body. This is why anxiety can produce literally every sensation in the book, because it is coming from our brain/mind and not the body.
Also, it seems to me that dizziness, lightheadedness, is perhaps the #1 symptom of anxiety. I do know that dizziness, lightheadedness is the #1 complaint of people entering emergency rooms.
The mind is indeed a powerful force!...
The best to you all!... Chuck
