You have a dream about someone that you may see everyday possibly at the office or the grocery store, and never really paid much attention to them as they are not your type at all until you have a sexy dream about them. Then all of the sudden for maybe a day or two you see them differently and maybe are even a little attracted to them, only to have the feeling fade after a few days, to which you come to your senses and think holy crap what was the hell was I thinking? Have I gone insane???
