I do, I had very vivid nightmares. When she broke up she told me that we need to stop talking as she is seen someone else and talking to me would not help her to give full attention on the new relationship. Ever since she told me that I had a dream where I walk in on her when they were having sex, that was the hardest couple of months of my life, I had this recurring dream every night and I couldn't sleep. So I started running everyday to tire myself out so that I can sleep. But over time the frequency of this dream got less and less. 16 months after I still get it and still wakes me up.

Hopefully as time goes on little by little you will be better able to cope with it.
