Fantasy or Obsession?

Well, I was just wondering about something. Everyone says that having fantasies is normal but is it a little bit on the obsessive side when you can make up elaborate stories about people, to the point where you look up previous dates on the calendar to see if they can coincide with your existing life?

You see, I must have a pretty vivd imagination because I have made up this elaborate fantasy or alternate existence involving Vin Diesel. Now I know that I will probably never meet him, but I think he is SO hot and I've made up a scenario where I've known him for years and he finally discovers me and falls madly in love with me and I can actually picture all this stuff happening.

This in no way means that I love my husband any less or that I am unhappy but I guess i'm a little bored and this makes me happy. I told my husband that I would jump at the opportunity to get in bed with Vin and he says that it is ok because everyone has those thoughts about celebrities. I don't know, I just didn't know if these fantasies are a little over board.
