For me dreams represent My kingdom i can change them as i wish the events,persons,nature,universe.At first i didn't know they are named Lucid dreamers and there would be some1 else as me, its funny to be a god in a world where you control everything but the bad part its when you wake up ,also i learnt that the dreams can be connected :)) even so i didn't reach that far yet
Did you have the dream just before or after your grandpapa died? In my mother’s culture the way I was born I'm suppose to be a ‘see’er’. You know. A person who see’s ghosts and can predict when someone would die. Lucky for me that is just superstition and I’m happy to report I don’t see ghosts. Anyways ‘see’ers’ sometimes have dreams of a person waving goodbye and walking away. That is properly a few days before it happens.
But I think you mend after your grandpapa died. If so, I’m happy to report your mind still remembers and ‘’think about’’ your grandpapa. If it was a good dream. Enjoy it.
