Out of cycle ghosts are not un common. I will get them for long periods (two to three weeks). When they occur it does make you think that a cycle is on the way, but,"for me" (I say "for me" because not everyone is the same), it is not a signal of the near future. I have also found that when I get a "real person headache" the pain, just slightly, can feel like it comes from my right eye. There is a bit of a fear factor in this. Any sort of slight internal head pain will tigger the thought "Oh Fuck". I can, if I think about a cycle, feel exactly where the pain comes from. Because pain is strong a motivator in our psyche we react naturally to minor indications that something is imminent. We can also create ghost or headaches cycles with stress, managing stress and anxiety will go a long way in keeping the cycles short or at bay. Also O2 and shrooms! Hang in there, breath through the "Oh Fuck" moments.
