zoned is another word for stoned or high,
as in zoning out because you're stoned.

When you are high (off weed) to the point that you literally keep "zoning" out. If this occurs while you are around other people, usually you will not participate in the conversation and instead sit and listen. Or not listen at all and just think. It can be very peaceful, but it can also make people wonder if you are ok and make you seem awkward.

The Zone is an ethereal state of mind that propels you from mortal man to super human, to godlike status. Performance, whether physical or technically challenging, is elevated effortlessly beyond your normal level. You feel no pain within your body and your reactions and balance become unhumanly fast. Things that were difficult previously become effortlessly easy. Failure does not even enter your mind and does not even seem possible. You soar with the angels and ride, tall and proud beside the god Helios, upon a golden winged chariot. You have become a god among mortal men.
Unfortunately the Zone is an ephemeral place and in the way that you unknowingly entered the Zone (you just arrive, you don’t know quite how), you are unceremoniously booted out of it. This usually involves collecting all the pain that you missed out on when in the Zone and dishing it out in one big serving. Once you have left the Zone it is commonplace to try and fight your back into it, but this never works and, in fact, generally speaking the zone gets further away the harder you try to get to it.
