Is it normal to love/obsess over a musician

I have a lot of favorite singers, but some of them I absolutely obsess over. I actually fantasize of living with these people or meeting them. I know so much about them, its like they're my close friend(s). And for the ones I'm attracted to, I often fantasize of having sex with them, sometimes even getting impregnated. I don't idolize these people, I just really love them and their music. I've been told my obsession is weird but I'm not sure. I know musicians have a lot of groupies, but I actually dream of being my favorite singer's wife. I feel weird when I realize that these are actual people and to them, I'm just a stranger/fan, but I feel like I know them personally. I know I might never meet any of them, but I don't think I'll ever grow out of these fantasies....
