Nope.
I'm a firm believer that if you truly believe in such things, then yes, they can "affect" you in the ways that you believe they will; and that its then very real for you.
But in the end it's all in your head, and it will only affect you if you let it.
Why walk in fear or paranoia over something that doesn't exist? Or even worse, believe you have some added super powers at your disposal.
Little learning for everyone:
