What should I do about the nightmares that I am having about my ex?
Why are you having nightmares about him, how does he look?
A brown haired man with freckles.
I also get nightmares about someone in my past, so I would recommend that you speak with someone about your nightmares about your ex. I'm always here if you need it to talk, or you can go with your parents, your other family members, or to a relationship counselor to see how you can move on from your previous relationship.
I should go with a therapist but I don't want to be told how to sleep.
It's great that you're considering going to a therapist. Some people believe that dreams are a way of receiving communication about something. Going to a therapist might help you to decipher what the dreams about your ex means.
