I Dreamt Of Grandfather Visiting Me

My dream started off random. I was in a hotel, my family for some reason was running it. I was going, before my parents divorced. I ran around with my childhood friend when my parents told me to go and shut off the water so they could do repairs. I went to the room and for some reason it was up on the roof. I walked across, holding hands with my friend, a long and thin sheet of metal. I looked down and seen the ground quite a ways below me and got scared. I seen a yellow and a red valve and turned the red. Hot water started to spill out from the roof. The platform I was standing on started to shake and I ran to my parents. My mother yelled at me and then asked if I shut it back off, I Said no and my dad went and shut it off. They said I emptied the hot water heaters and if it was any longer they would explode. My dream then cuts. I thought to myself, 'oh I'm starting to wake up,' but that was not the case. Next thing I know I'm standing in the middle of a dark room. A candle sat infront of me and I pulled out my phone, but the camera was on. In the camera, my grandfather appeared. He died years ago, right before the divorce of my parents. He smiled at me, hugged me. I could feel it, it felt so real. He told me how proud he was of me and that I am so strong for doing what I'm doing. He told me he loves me and that he misses me, but it's not time to give up. He told me I am a great daughter, a great girlfriend. He then wanted me to relay a message to my grandmother saying that he loves her more than anything else in this world and that he is waiting for her. He reminded me that he is watching over me and that I'm strong. He told me loves me, than he hugged me again. I woke up feeling so calm, but I could still feel his touch, hear his voice, see his face. It didn't feel like a dream.
