I suspect he means this kind: http://en.wikipedia.org/wiki/Apple_box

The first "proper" job I had (contract, responsibilities etc) I used dream every night for weeks about work. It wasn't the horrible not-prepared or showed up naked dreams, just regular work stuff, over and over, multiple dreams each night. And yet it was stressful (and irritating), because it felt like I was doing 8 extra hours work, and not getting paid for it. wabbit89 might be onto something about getting a friend's help with the dream. I used to have pretty frequent nightmares about a person from my past until my sister told me dream her into those dreams with a baseball bat, where upon she would sort him out (she's not at all violent in her waking life, I feel I should add). I don't know if I could have done it, but I didn't have to. The dreams stopped after that. I don't know what the real-world solution to that kind of situation you dream about might be, but if you can think of something and get someone you trust to help, maybe your brain will stop serving up those dreams. But on the other side of things, I occasionally have funny stress dreams. I once had an incredibly vivid dream that I was in the US Navy, and had been on leave, but that I was supposed to be back in the Washington Naval Yard that morning. I woke up still convinced -- because it was so vivid -- that this was the case. I woke up in my bedroom in Ireland, 3000 miles away, thinking about how fucked I was. Reality kicked in pretty fast, but there was a genuine moment of OMG whathaveidone? panic. But the whole thing felt so surreal that I wound up finding it hilarious. Like my brain was pranking me.

My thoughts on current security theory have been thoroughly covered by others (I fall firmly on the it-doesn't-protect-our-freedoms-it-erodes-them end of the scale), so I just want to say how sorry I am that this happened to you. If I may, I would also like to suggest not paying too much attention to those who tell you what they "would have done" in the same situation, or criticize you actions or reactions. It's mostly nonsense, and even where it isn't, it's still meaningless. It's pretty much impossible to prepared for this kind of thing to happen to you. Maybe you'd have done something differently if you'd known in advance what would happen. Maybe you wouldn't. We get through it how we get through it. You didn't do anything wrong.
