Dream #144

I've been with my girlfriend for three months now. We are both very open to eachother and are deeply in love. But reciently, she had a series of dreams where she cheated on me, 3 times. In her first dream, she cheated on me, by having sex with another woman, and later, a talking bear. And that same day, she had another dream where she cheated on me, by having sex with a 50 year old man in a cannoe in the middle of the ocean. She says these dreams make her uncomfortable, and really wishes they would stop. They also make me uncomfortable. Does anyone know anything about this? Are we just freaking out, or is this brought on by something?
