Beck, I used to have dreams like that very vivid too. The weird thing is about 2 years before I even thought about any doubts, I started dreaming I was on the other side . I could see some faithful witnesses on one side of the ground that had split into, I would just stand there and be heartbroken.
Once I left the borg , the dreams got even worse. It has been a year now and I havent had any armeggedon dreams here lately.
Sometimes it crosses my mind that the big A might hit, then I refuse to think about it.
Right now I don't give a flying fig newton, about it all.
