He said I'm his dream girl?

My boyfriend of a year and a half told me last night that I'm his dream girl. I was flattered of course, but I do know that his type is definitely blonde/blue eyes when I'm brunette/green eyes and pretty average looking (nothing special). Do guys just throw this stuff around or is there a possibility that he really means it? I love him so much so if he honestly meant that I'd be so happy.
