(in terms of introspection): to look through one's soul as if it were a tunnel and see nothing but darkness and despair.
depression and drug addiction are hard to treat in part because the depressed and the addicted often have tunnel vision when it comes to introspection and think that there is no way out, so much so that they are even afraid to go and ask for appropriate help.

"Tunnel vision" is when a World of Warcraft player stick on one target in arena and doesn't switch at all. Kind of walking straight down a tunnel.

When two guys have sex with the same girl, but at different times. Similar to eskimo brothers, but warmer and not as racist.
