Just to throw my two cents in......I was having trouble with sleeplessness, experiencing paranoia, a sense of unending dread, terrifying vivid nightmares and ended up being hospitalized earlier this year. It turned out to be a horrible reaction to my meds, and it took a change in psychs to work it out.
Might be worth looking at your meds, have they recently changed? Has anything else happened that could have triggered this?
