Mine are frequent and extremely disturbing many times. I have to kind of gauge what my state of mind is before (trying to) sleep, whether or not I should take a prazosine. They make my BP bottom out and make me very drowsy the next day, which I can't stand...it makes it hard/impossible to function the next day but at least I don't remember my dream at all and I have never had a night terror whilst taking...The night terrors I typically don't remember, but they get my up immediately with racing pulse and cold sweat. Any hope of getting back to sleep after one is dashed. Often I have creepy and vivid dreams of either being back in my old unit, or at least some of the others from my unit (always the offenders) are present and I am trapped in whatever setting with these people and I am trying to escape. I wake up feeling gross, sometimes the result is me sleeping longer (on purpose, I think) so I can maybe, maybe finally escape...yeah it doesn't work...
