Discoloration

I had a dream of a old freind who passed away abou 5 years ago. She was sitting in my lap and we were holding eachother. She was rubbing my face and kissed my cheek and told me she missed me today. Then i walked up stairs still holding her, she wasnt touching the ground. And her eyes went black as she hissed at my sister.(who is very scared of ghost and such) so i talked her back to who she normally was, and she went back to rubbing my face and hair with her normal eyes. I then sat on the couch with her beside my father(who has been very ill for a few years now) and she still in my arms reach out for his hand to shake it, and he said he was not ready to shake her hand yet, her eyes went black again and i had to talk her back to normal again. when i woke i was holding my own arms around my body and felt completly warm even though i had no covers on in the middle of winter(canada). when i finally decided to stop hugging myself it felt like the room and walls were miles away. also in the dream when her eyes were going black her voice was of my ex, and her face was inbetween persons. the dream felt like 12 hours but in reality was only maybe 2 hours. This is one of the most vivid dreams i have ever had. please respond
