Dreams about them

2 weeks ago for 5 nights in a row I had dreams  about my deceased Father and Mother.  I can't remember about the contents of the dream, except for 2.  In one dream father and mother were walking on the road going towards our old house. They had done a lot of shopping.  I stopped my car to give them a lift, but they refused. They said "you don't really care about us".  In the other dream Father was pleading with me that he wanted to go home. Mother was quiet.

Each time when I woke up from the dreams I felt very exhausted.  I shared my dreams with my sister. She said I am so lucky to be able to dream of Father and Mother because they had never appeared in her dreams. I complained to her about the exhaustion I felt upon waking up from the dreams. Since then, the dreams had stopped.
