It started a week ago maybe with this feeling as the boundaries of I are mixing with the space around me. Then two nights ago I felt this intense energy while singing as if it can shoot out the top of my head. I was frightened and I thought it will be temporary. Now it has been building it feels like with more and more intensity. I feel like my whole nervous system can shake from how intense it is. I have felt hot and cold energy in my spine. I feel as if I can make out vivid images of galaxies stars planets ect. I feel love and peace and bliss then Intensist as if my body is being ripped apart. It is super debilitating and I don't know what to do. Does anyone know about this or any advice.now it is day 3 and I feel it building as I wake up. It it is hard to talk, or do anything. Anyone know how long it can last or how to slow it down. I am not on any substances nor do I have a history of psychosis
