I've known this for a very long time, knowing that our perceptions, thoughts, emotions and words can all have an affect on our minds and bodies. Be it negative or positive situations.
Things like, what you put out there into the universe you get back at least 3X back. The same goes with our bodies and mind. If we respond to someone's greeting by saying, I am meh, then you will be meh. But if you say you are happy, healthy etc, then you will be.
So when MSM change our perceptions by feeding us lies and other negative stories, it creates the negative emotions which build stress and anxieties. Our thoughts on those stories change how we think and then changes the way we are by becoming what is put into our perceptions.
