According to a research, on human psychology, it's observed that, human brain accept those things which he/ she wants to,in lucid language we can say that, whatever is our mindset, that will reflect in our surrounding,
For example, if a person is regularly watching investigation tv shows n films, he/ she will have that type prespective towards their surrounding, they will suspect every single person around them! Most of u even felt that in real life! Human brain is a complicated connection of neural cells, which can't distinguish what's real, what's virtual, sometimes that tv shows/ films we are seeing we feel that Character, that personality, inside us
N this is completely normal, as an example when we are listening a song, we connect our emotions with that song, we started recalling all the past memories, so what we are seeing in tv shows / films that's highly affect our thinking ability.It's not about the tv shows but about those unrealistic relationship, they build up in social media sides, n there are so many reasons of failures of this kind of relationship. So try to distinguish between real and virtual things
