This is a little trick I like to call "Sleeping like a snake."
You would think that my head just happened to slip off the couch this one time and that I never woke up to realize what happened. Nope. I sleep like this a lot. It is comfortable for me. I like to use my long nose to hang off the couch while I'm laying with the people. It's my couch, I can lay on it however I want.
That's why the people like to call me "Long nose face." Of course, it has its disadvantages. Not more than five minutes before posting this I ran my nose into both a metal chair and a door frame just from swinging my head around to look at stuff.
