Curious if anyone has experienced something similar to me. A few years ago I was with friends at a music festival. We were all sitting in a circle at camp (i took dmt & ketamine) when all of sudden the floor and everything fell beneath me and I was in an endless white room or void? There was nothing. Absolutely nothing but white. I was terrified and apparently started screaming "help me. Help me. Im dying." I remember trying to "close" my eyes hard when I was in this state. When I came back I was on top of my bf who was sitting next to me. I apparently climbed and clung on to him. Has anyone entered this white room or void before?
