REM
REM is short for rapid eye movement, a sleep-stage term described by VCA. Knowing the term does not let a reader or this website identify the stage in a particular dog. No eye check, sound test or timed observation is offered. The bookshelf explains vocabulary without making an animal available for examination.
Evidence
Evidence supports a defined statement, not every related story. VCA discusses the general case for dreaming in dogs. That does not reveal the specific contents of an individual dream. Dogs Trust preserves uncertainty about what a dog experiences. Neither source makes our fictional captions patient evidence or validated outputs.

Interpretation
Interpretation adds an explanation to what is described. The caption editor shows how a fictional account can overreach by claiming a dream plot or a health verdict. A narrower sentence keeps those unknowns visible. It cannot decide whether professional help is needed in a real situation or replace that help.
