Dreams keep bringing back memories

It has been exactly three months today since she broke up with me. I used to dream a lot about her when she broke up with me, but they're coming back again. I've had a dream about her almost every night this past week. I've felt like I have been doing so well recently, but this week has been a struggle because of it. It's really a burden going to sleep when you are afraid of having another dream about the memories we had.
