i have also had dreams of people from the past who i had relationships with, friendships, etc. that ended or times i knew them were very emotional for me. they are upsetting because i always think i'm finally over them and the situation, but i still dream of them every so often years later...one friend in particular who i was best friends with from 12 to 19 years old and our friendship ended a few years after high school since we grew apart and stopped talking, etc. i thought the very last conversation we had healed those wounds, but i found she blocked me on social media..not sure why....it still upsets me when i dream about her though because in most of them, it involves her either coming back and we are friends again or she is leaving and i am crying.
