As you run nautilus with sudo, you are running it as the user root. This user has it's home directory at /root.

Try to run nautilus without root, i.e. as a normal user (by simply typing nautilus), and your "Home" will be at /home/username. Your "terminal user" will be your normal user account.

Please see the sudo man page
