What's Wrong With This Picture?

I work long hours at the hospital. After a 12 hour shift, it's nice to have a comfortable place to sleep. But here I am for some reason sleeping on the couch and when I wake up and go upstairs to my room, I find my dog sleeping on my bed. Not sure how he got the comfortable place to sleep but there is something definately wrong with this. I can't believed I got booted from my own bed and by a dog!
