Feeling the field doesn’t mean anything.
From the Official FAQ:
And a lot of the field’s effects don’t have any sensations to them when they naturally happen to your body, so you’re not going to “feel” the field in that way either.
What you will feel, when you use a field more than the recommended usage, is overload. You might not feel that right away. When and how you will feel it depends on the condition of your energy systems. When there’s a usage recommendation in a field’s description, it’s best that you follow it. It’s there for a reason.
