Last week, I had 4 consecutive nights where I had dreams I was dating either one of my male friends, one of my male workmates, a male friend from uni, or one of my exes, all of them I have been attracted to at one point or another. In all of the dreams, the relationship I was having with these guys was new, as in the first few dates.. In the dream about my ex, I remember thinking, why am I going back to him? And in the dream about my workmate, he was telling me about his daughter.. but he has no children. In the dream about my friend from uni, we were really dressed up, and standing in front of a mirror together. I'm in a relationship, and in my dreams, I was trying to figure out how to tell my boyfriend I was cheating on him and how we had to break up. I have been having doubts about our relationship, so I'm thinking that maybe this is my subconscious agreeing with me? Interesting.
If you are having doubts your dreams could certainly be trying to fill your thoughts with ideas of being with someone else, even experimenting with the idea of being with other people you know. It is quite common though for people to dream about relationships with other people, friends and friend's lovers, even when they aren't having doubts. It's normal for your mind to wonder what life would be like in different situations.
