Was that the one with the guy and his junk in the meat grinder? I own that! It was eventually released as a part of a box set around '96. Gotta love NIN.A long time ago I watched a fake snuff video by Nine Inch Nails because a boyfriend (ex now) wouldn't tell me what was on this vhs tape so I popped it into the video player and found out by watching. By the end I almost vomited and then I had nightmares for a while. He had bought it on the streets of San Fran; it was a rare edition not released to the general public. The FBI proved that it was a fake. Even so, it's part of the reason I won't watch the 1 Man 1 Icepick video; I know I won't be able to handle it.
Judging from my experience with the fake snuff video, I'd say that in time you will probably feel relatively normal again. You just might be more cautious or fearful than before. It takes a while for the mind to shake off the creepy associations (the atmosphere) it picks up while exposed to subject matter like this. We all probably need to take a break from it.
Yes, I know I feel better when I get away from this for 1/2-1 day. But thanks to WS I feel compelled to get on here to keep abreast of the conversation! Trust me, I have very thick skin when it comes to gore. This case is just a trip!
