There is always a contradiction that “what u see is not what you get”.
This is a part of the eye illusion, i just found this in one of my favourite you tube site. An illusion is a distortion of a sensory perception, revealing how the brain normally organizes and interprets sensory stimulation. While illusions distort reality, they are generally shared by most people. Illusions may occur with more of the human senses than vision, but visual illusions, optical illusions, are the most well known and understoodHere is an illusion video through which you can see a hallucinogen. In this video you will find it really weard, but its only our perception.
Dont be scared, cause i was a little. It amazed me when i tried first time after that, started knowing the fact. Anyway just see it and realize….
