I suppose if someone were to make these arrangements while on Ambien, in a remarkably focused somnambular state, one might say the person was unconsciously aware of impending death. But “subconsciously” just doesn’t seem intelligible here.
of, relating to, or characterized by somnambulism
- an abnormal condition of sleep in which motor acts (as walking) are performed
- actions characteristic of somnambulism
Oh, so you mean…
(Medicine) relating to sleep-walking
And of course:
The word I was actually unfamiliar with in the Magister’s passage was Ambien:
Zolpidem (originally marketed as Ambien and available worldwide under many brand names) is a sedative primarily used for the treatment of insomnia. It works quickly, usually within 15 minutes, and has a short half-life of two to three hours. Zolpidem has not adequately demonstrated effectiveness in maintaining sleep, unless delivered in a controlled-release (CR) form. However, it is effective in initiating sleep. Its hypnotic effects are similar to those of the benzodiazepine class of drugs.
