The plaid super highway

Whenever I would hallucinate on Ketamine it was always the same thing. Loops, falling, flying, giant beings coming out of the walls like a mirrored image and guiding me through ancient forests and giant rock structures so I gave it a name. The plaid super highway.  Traveling down this highway became a regular and familiar and welcomed feeling. I'd just lay back, focus on one thing and we would go on a trip on the uber dimenional highway for up to an hour.
