For instance, @temp_sleep me is "sleeping here, propped up against the wall clutching a letter."
This would display instead of your regular @sleep_place me UNLESS you are (a) moved or (b) your body is manipulated in someway (looted, pickpocketed, something is planted on you, etc.), in which case your normal @sleep_place me is displayed. Maybe some flavor text could be added to signify this change, like "X rolls around in their sleep, readjusting themselves." or something to that degree.
I think this would be pretty useful to have and would love to see it added.
