When im relaxed and concentrate, i start to see different colours that often turn into shapes. I then feel like im zooming through a long and winding tunnel. I can feel energy all around me as my eyes start to flicker. I feel tingles in the palms of my hands and up my arms, also my face becomes numb and feels tighter. I would really like to know if the tunnel leads anywhere?
I have seen a butterfly shape if that means anything??
