When i focus on something white it starts to slightly vibrates. i feel shakiness inside my head & whole body, it doesn't show the shakiness just feels?

Just white?: Do you mean when you look at something that is white in color, you feel uncomfortable and shaky? And that no one can see this is happening? This may be a symptom related to your thoughts. This does not mean you are ill, but it may help you to visit with a psychologist to talk about this symptom that is bothering you. Then it should be under control.
