me and my ex just recently broke up...and i've been having very vivid dreams about her having sex with guys that used to be my friends...the last one i had was last nite, and in my dream i caught them...when i woke up i was so angry...now in the past when we had split up, my supposed friend and her had sex. we were only supposed to be taking some time off to try to work on our relationship...why do i keep having these dreams and why am i getting so angry?
