Dog
The domestic canine operates with clockwork predictability. Feeding times become sacred appointments; the 6pm walk occurs regardless of existential crises or global pandemics. Studies indicate dogs recognise their owners' vehicles from 400 metres distant, positioning themselves at windows in anticipation. This reliability extends to emotional availability: the dog offers consistent affection without mood fluctuations, personal grievances, or the need for explanatory conversations. The dog shows up. Every single day.
Dreams
Dreams, by stark contrast, operate on a schedule determined by neurochemical chaos. One night delivers a vivid adventure narrative; the next offers only forgotten fragments upon waking. Researchers estimate humans experience 4-6 dream periods nightly, yet recall fewer than 10% upon morning. Dream content follows no discernible pattern: examinations unprepared for, teeth falling out, deceased relatives offering cryptic advice. The dream cannot be summoned, scheduled, or reliably predicted. It arrives on its own inscrutable terms.
