NIGHT NOTE 02
REM is a stage, not a story
Rapid eye movement gives REM its name. It does not give an observer the script playing in a sleeping dog's mind.
A name for a pattern
Veterinary descriptions distinguish quieter slow-wave sleep from REM sleep, when brain activity and eye movements differ. These are physiological descriptions. They are useful for explaining why a sleeping animal is not simply switched off, but they are not a set of household instructions for identifying every stage by sight.

The visible part is incomplete
Small movements and sounds may occur during sleep. A camera shows visible movement and records sound; it does not directly record sleep-stage brain activity. Avoid relabeling every twitch as confirmed REM. An observation can be accurately described without assigning it a stage at all.

No stopwatch prediction
Some general articles give average timing examples. This publication does not turn them into a countdown to a dream, a normality threshold or a schedule for filming. A population-level description is not a personal timetable. Timing an actual worrying episode for a veterinarian is a different task from predicting dream onset.

Different questions need different evidence
Is REM present in dogs? What did this dog experience? Does this episode need medical care? Those questions are not interchangeable. A general sleep article helps with the first, cannot directly answer the second and cannot replace a veterinary assessment of the third. Keep the question visible when reading an answer.

Read the margin
When you see a confident dream caption, look for the missing qualifier. Probably, suggests and cannot know can be precise words rather than weak ones. They tell a reader where the evidence stops. This site keeps that margin attached instead of removing uncertainty to make a more entertaining headline.
