Richly Coloured Dream Surfing

I had the most real and intense dream the other night. I dreamt I saw my Grandpa again. (He died quite a few years ago when I was in my mid teens). He was younger and healthier than I had ever known him. He had been away for a few years and I wondered why he hadn't contacted me for so long. But he was so happy and delighted to see me. I woke feeling sad that he wasn't around anymore but touched that I had experienced such a vivid dream about him. He would find this strange modern techno world so interesting if he could see it today.
