Emotions are easy; <person smiling>, <person frowning>, and so on.
Hot: <person wiping sweat from brow>
Cold: <person shivering>
Unstable: Like all adjectives, needs to be attached to a noun; "unstable ledge" is <ledge shaking with exaggerated instability>.
Danger: <image of an example of danger suitable for the current situation> (which would be translated appropriately; instead of "Don't lean over the railing, it's dangerous!" you'd get "You might fall over the railing!")
Near: Both objects are imaged next to each other
Far: <object1> <person moving some distance> <object2>
Now: <Image of current situation at current location> (also could mean 'here')
Before, after: Two events are imaged in chronological order.
Unknown: <Impression of movement from amorphous mass which purposefully dodges echolocation pings>
Of course, there's also Light and Dark. They're sort of central to the character, and the best I can do for them is <eyes squinting in bright light> and <eyes wide open, pupils dilated, big smile>.
