From young until today, i have met many friends that have this capability to see spiritual not from this world. Beside In certain show that they even can describe the same image as two persons got third eye as validation.
In the eye of many people or even main stream science today. Third eye is may be a person may have be kind of health disorder but it is not proven. But yet, they are many cases of these people able to see this kind of spritual images commonly.
Are they nothing but they are just energy from other dimensions. They are the result of after life? Or it is just another living kind but we are able to sense it via weak gravity?
