I have an app on my phone (called “CVSimulator”) that represents types of colorblindness. I’ve shown it to people who are actually red/green colorblind and got confirmation from them that it’s pretty accurate.
Red/green colorblindness in humans can be either protanope or deuteranope. I’m not sure which one dogs would have (if someone is more knowledgeable on this, please chime in!) However, this is how my app interprets this image. The top is protanope, the bottom is deuteranope:

So it’s a little off, but some of the colors are correct.

























Wet dreams? Though when I’m sick, congestion seems to disappear when I sleep (only to return after I wake up.) So if that’s normal and if wet dreams have some kind of decongestant property, we may never know.
