Dreams Becoming Reality

My grandmother passed away last Feb. I kissed her on her forehead and was shocked. I don't know if this has anything to do with it, but since then I have had dreams and people in my room. The first dream was her funeral. I was there and their was this man there, unknown to me who he is. He said to me that the dead talk very slowly only about a word a year, and I have put these words together for you. She said to me that its not what people think, its not beautiful. Last night I had another dream. This one did not bother me because I am so used to it now. It was just her in the coffin and she was moving around a bit, trying to say something. The thing that scared me was the feeling I had when I woke up. Someone was in my room. I saw two people at the window, then they were inside. I am not crazy. I know that out of my family, I would be the one to come to, because I don't really believe in anything. I am open to whatever. Last night after the dream I just felt this bad feeling around me. I don't know what she wants. She was not an evil lady. She was catholic. I just feel that she needs me to do something or know something. I just don't know. If someone knows what this means please let me know.
