I like to share the mechanism by which how these able to control some individuals.
Here is a test to see if you are prone to these.
Imagine current year is 2000. Keep repeating in mind as if its real. If you start to feel like 2000 then your prone to these. How quickly you believe determines the extend. If very quickly then delusion chance high. If less quickly with doubt then intrusive thought chance and so on.
This is why some individuals believe in their doubts, story, plots, ideas etc so deeply as they quickly believe in it. Dopamine has a part as it helps individuals to focus, thrive on their ideas and goals.
So if anyone want to prevent such negative aspects then think logically to see if its practical or not, compare with lives of other people etc and once it found false then manually not focus on such, instantly dismiss it even though the urge and feelings there.
