I became a demon?

Date: 2/18/2018

Has a dream I was this Japanese girl still in high school . I am in love with my best friend and there is some fun tension between us. The dream turns though to where I find out that I’m this weird demon monster that is supposed to stop this army and plague that is about to hit the world. I then find out my best friend had been my guardian all along and he starts to train me how to use my powers. We also start dating haha. So the rest of the dream is a race against time , but monsters are still getting out and stating to go on killing sprees . The dream ends with me still training, last I remember is another “love interest” comes into play for my boyfriend which I later find out it is just me from the future trying to help with my training. Overall a weird dream
