noun: The sun, heat, noise, dehydration, lack of sleep, and any chemical/alchohol based rampages you may have been on *may* affect your cognitive abilities at some point during your burning man experience. Playa Brain may cause you to: make bad life choices, make good life choices that you never would have otherwise considered, lose your keys, find Jah, forget you long term life partners name, ditch the thing you’ve been planning on all year to spend the night with a dubstep DJ, or even high-tail it for the nearest city.. There is no predicting how a burn is going to go, even for an old dust for blood. Sometimes it’s going to affect you more than others and you are going to make choices that you wouldn’t otherwise. It is not uncommon to see virgins too overwhelmed to move, and jaded veterans moved to tears. Expect the usual tricks that your brain plays on you when you are over-tired and over-stimulated, then multiply by the amount of chaos affecting your personal burn experience. Prepare for Playa Brain the best you can, hide a spare set of keys, and try and go with it, have a nap an Emergen-C, and more water.
