Is there a term that is similar to "placebo" but doesn't imply a medication, simply an imagined effect due to an observed phenomenon?
For example, say I hear someone in my office say they got bedbugs over the weekend and they're covered in bites; it might make my skin crawl and make me itch my own skin. Or if I eat a meal and feel fine but someone who eats the same food feels sick and tells me after the meal, then I may feel sick as well since I'm imagining something was wrong with the food when it actually sat perfectly fine in my stomach.
Is there a word for this?
