Can anyone interpret this dream I had last night?

I believe this dream was about my Nana and an Aunt that I haven't seen in almost 10 years. My Nana passed away in 2004, she had Dementia and was in a nursing home. This Aunt is my Mom's sister and she started to develop Alzheimer's a few years before my Nana passed away. For some unknown reason, my Aunt's daughters (my cousins) would no longer allow my mom and other aunt to see her or be in touch with her. These are her sisters! So we have had no contact with my aunt or cousins for a really long time. I have not been thinking about them at all - Last night I had a dream in which my cousins and sick Aunt were getting angry with me telling me that it's my fault I haven't kept in touch and I should have tried harder to see my sick Aunt. In the dream, my aunt wasn't sick anymore. We were in a living room or something then suddenly I was standing on a busy dock where there was a small boat. Standing beside me was my Nana, she was still old but dressed to the nines in a cream suit/dress, hat, and shoes (looked a bit like the Queen - Nana loved the Royal Family), her makeup was done also. She didn't say anything but she smiled at me and I hugged her. Standing next to her was my aunt. I don't know if they actually got into the boat because I woke up. I don't know what this means - Anyone have any clues?
