I was on public transport riding home suddenly this fear came on and overwhelmed me. I felt like I was being separated from my body. I then saw a water tower and the antennas on it looked sinister and menacing. I quickly came to believe that this was a concealed nuclear device, among thousands scattered across the country. They would soon launch into the air and start a nuclear holocaust. My heart was pounding I maintained control of my body and avoided quick and sudden movement. Eventually I got home and the feeling wore of but it was frightening. Anyone else experience something similar?
