I had a dream of grandma she came to me and i told her that im sorry i haven't went to the cemetary to see her and she told not to be because ill be wasting my time, don't waste your time since theres nothing there anymore, i ask her if she could see my cousin that also passes way and she said no i can't but when i ask her i she could also see my stepbrother that aslo passed away ahe shes i could see him, what does this mean? then she said she had to go now and told me that i was going to do something and left, then i woke up!!!
