i have the same dream fairly frequently, occasionally twice a week, and i always wake up in a cold sweat from it with my heart pounding
basically what happens is I am always in a social situation with my friends, and my girlfriend is there. (been going out 5years and are prob gonna get married). She suddenly starts to strip, or is suddenly naked and i panic, trying to cover her up but she wants to dance about. Everyone sees her and i am mortified, and more than a little cross.
then i generally wake up in a panic thinking a little badly of my gf for it in real life (altho this only lasts about a minute)

its fucking strange that it keeps happening!! I dont even think it relates to real life cos she would never in a million years even dream of doing somehting like that!!
