NIGHT NOTE 01
Why the answer is probably yes
The interesting answer has two parts: dogs have sleep physiology associated with dreaming in people, but we cannot interview a dog about the experience. Keep both parts in the same sentence.
Evidence is not a conversation
VCA describes similar sleep stages and electrical activity in people and dogs as evidence for dreaming. That is a reasoned inference from physiology. It is different from a person waking up and telling a researcher what happened in a dream. We can respect the evidence without pretending the missing first-person report exists.

What the comparison supports
REM sleep is not an invented label for a funny paw movement. It names a stage studied through physiological signals. Texas A&M describes REM in dogs and the difficulty of knowing their subjective experience. An owner watching from the sofa has a different kind of evidence from a sleep laboratory.

What stays out of reach
A sleeping dog cannot confirm that the scene involved the park, another dog or the person beside the bed. Familiar daytime experiences make an appealing story. They do not turn that story into an observation about this particular nap. Leave the plot in the category of affectionate speculation.

A sentence worth keeping
Try: evidence suggests dogs dream, but I cannot know the content of this dog's dream. The second half does not cancel the first. It prevents a broad scientific explanation from being used as a personal mind-reading claim. That small distinction is the starting point of this publication.

Curiosity without interference
There is no need to wake a sleeping dog to settle the question. VCA recommends quiet, comfortable and undisturbed rest. You can read about sleep while allowing the animal to sleep. If something is new or concerning, the useful next conversation is with your veterinarian, not an online dream interpreter.
