Deceased people in dreams

Hi all,
Never even looked in this forum before but I was wondering if anyone has been visited by a deceased person in a dream? I dont just mean that someone who passed away was in a dream u had, more like that it seemed significant or that they were giving you a message or something? I've been upset lately over a member of my family who died last October. Then I dreamt that I saw her again and she was telling me not to be sad and be happy and a few other things. I didn't wake up with my alarm (which I always do) and I didnt even remember the dream till I was nearly at work. I know it's probably just a subconcious thing - like I know if she could talk to me she'd say them things so it's probably just all in my head. Was just wondering if anyone else had any similar experiences?
