For some time now I have vizualize a "thing" blocking my third eye, leaving me blind to most things outside this world. Exept on dreams, in which appears to be a mask made of metal covering the top half of my face, the mask is a three spiked crown. Even thought it was my own idea or a subconscious image but I found few people with astral vision that could saw it to, but not touch or afect it whatsoever. ¿Whats the nature and porpuse of this thing? meditation strengthens the chakra but I can barely see fumes in the dark with eyes closed.
