I remember this story of a family:
Their children had some health issue and had minor surgery. One day child texted her mother " mom I can not see when I close my eyes". They had couple texts and finally she realized what she mean"
You must be an open-minded person to understand and must look at it as much as indifferently you can. Also must have a mindset of using logic. If you lack these, you will not get subject matter but end on your pre-occupied mind. Pre-occupied mind makes people behave weirdly.
