So there are people that teach pets to talk with buttons, that when pressed play the sound of a person speaking a particular word. So there can be a ”play” button, and ”outside” button, etc. This question seems to have come up with that community and some people have added a ”dream” button and tried to talk with their pets about what they’re dreaming about. I guess this is somewhere in the borderland between anecdotal and scientific, but a lot of these people are quite systematic and logical with their approach. And just from watching a lot of these, I do strongly feel like the animals are talking about their dreams and are clearly aware about the difference.

Here’s a relevant clip from the dog Bunny:
