Never was in one as an inmate but put many there over the years but other than being in a prison camp in North Vietnam for a while, being imprisoned is no fun at all and is actually compared to a nightmare from he.l, its like being in a dead zone with no life, no moral, shut off completely from the outside world, living like no human ever should, having to watch your back everyday and night for various reasons but mostly just to stay alive, being forced to be someones pet. One loses all emotions in prison which is why its so hard to re adjust to life when getting out
