Two techniques from my experience: - 'walk back' in your mind to center yourself away from forebrain activity and visual activity (this is a visualization technique) - cover your back with something insulated and/or warm. The less your back is staying tensed against chill air, the more physically relaxed you can be. I have a Thinsulate-filled sleeping bag that I use like a throw for this as it reflects body heat bett…
Could you please expand on the "walk back" thing? Also, any links, books? Thanks.
When I close my eyes, almost immediately my visual memory lights up with a "day review" which is like a daydream but for being something which I can direct, using pretty much the same visualization mechanism I use for data/code/schematic structures when I'm designing, coding or debugging. I can feel that forebrain activity as a slight heat just behind my forehead. It's great for overview and casual entertainment when I can afford the time, but not when I need a quick nap and it's keeping me conscious.
I will the main weight of my awareness to recede from that frontal visualization viewplane, moving toward the back of my skull, deliberately dissociating from the visual activity, to where things feel like they're quieter and move slower. If, for motorcycling, where a less tightly-focused, more panoramic viewpoint is best for situational awareness, I take a half-step back, for quick napping I take several steps back.
You can forcefully imagine the footsteps if it helps establish the change of center; after awhile, that mental positioning becomes familiar enough to dispense with the imagined physical/aural sound-effects.
Sorry if it sounds all too Crafty or New-Age, but that's how I live.
