As someone with OCD anytime I hear advice about behavior or thoughts I immediately think of how that advice would apply to OCD lol. I think it’s almost like a part of OCD. Realistically it is probably just talking about the conscious thoughts you intend to have and not the unconscious thoughts you randomly have. I have noticed a correlation though that advice that would negatively affect someone with OCD is normally just bad advice because everyone has unwanted thoughts and feeling.
