It is like a thought, but not a specific one. It makes me jump, but it is not something "physical." It is not conscious, because it has awaked me from sleep. It sometimes appears when I am awake but fine and relaxed. It is anxiety provoking. I remember having this feeling when I had high fever as a kid. In my dreams, lines, circles and other basic shapes made some endless monotonous movement, or turned from order into chaos. And I wanted to stop it but I could not. I was never concerned about this because I thought it was something temporary associated with a cold, flu or other common minor illness. Around two years ago, and during the period that led me to the discovery of my addiction to PMO, I started experiencing this feelings randomly in my wake life. So I think it is like the seed of a panic attack. I had panic attacks last year and early this year but they seemed to be fixed after a couple of months into my reboot. Now I have a bad cold for nearly a week and yesterday and the day before I had this feelings again. I hope they will go away when the cold is over, but the fear is paralysing. Can anyone relate to this?
