How can rearranging your room make you feel so different?

So ive changed my room around like 5 times since I moved in. And each time was good, but I still hated my room like I didn't like walking into it I just didn't like the feel. But this time I changed my furniture in a different way and I love it so much, it changed the atmosphere of everything and now I even woke up early happy instead of sleeping in evert day waking up depressed. I'm just wondering is this like feng shui? Or something? I wanna know why just changing your furniture can change yourself.
