I get these if I stop smoking weed. Couldn't smoke during a school trip to the States years ago, two of the other people I shared a room with also smoked regularly, all three of us had fucked up vivid dreams for the entire week. I still remember the one on the first night all these years later. I remember vividly watching myself disintegrate while a nuke went off nearby while I was working on something at school. My dad's also said nicotine patches do the same thing while you're on them.
