Every time I hear or see...

[ooflendoodle]

Can someone tell me what this is (if this is a specific "condition" or if you have the same problem, and how to overcome it? Every time I see pictures of the body (usually the endocrine system) or hear about the body or nasty diseases, or meditate or try to listen to the brainwave stuff that helps lucids. My feet start tingling and I feel weaker and jittery and really uncomfortable.
