Just Weird Feelings

I don't know why I feel the things I do but I do. Sometimes it is a dream or just a flash. I don't have them very often but when I do there usually right. I had a dream about my grandfather sitting on the end of my bed with his arm around me then my grandmother who past away about 17 years ago came in the room put her hands on my shoulders and said everything will be fine. Then grandpa stood up said I love you and walk away with my grandma. Then about a month later I found out that my grandfather had stage 4 cancer and was going to die. At that point I knew what my dream meant. My grandmother was telling me she was coming to get my grandfather. My mother and cousin was in charge of taking care of him while he was sick. It was shortly after New years that my grandmother came to me again. This time I thought I was awake but not sure if I was for sure. I woke up and my grandmother bends over to me and says, "help me". My mother called me a few days later needing a ride to the cancer center to start his treatment. He did not want the treatment because he knew it wasn't going to help him, Doctors were pushing him into the treatment and my cousin and mom couldn't get the doctors to stop asking my grandfather about the treatment. This is where I took over his care. He passed away three months later.Don't know what to make of all that. I still have my grandparents come to me in dreams when something bad is going to happen but I never know what, I think its just to prepare me for the worst.
