Spirit Guide

I always paid attention to my 6th sense. Maybe not so much, but more then my family did. The first time I think I met my spirit guide is when my grandmother died. In right before they where ready to put her in the ground. I heard her say the nick name only she called me. So I looked around. To myself I am like I know I am not going crazy, but she said to me grab a flower, so I did in walked away. Ever since then my grandmother visit me in my dreams. In dreams she is always preparing me for some thing. In the most resent dream she had came back from the dead for like a day in spent time with the family, but that dream was a week before my boyfriend died. His death was ten days ago, but I still feel him here... I have not been home alone since he passed because I can feel him watching me. It don't matter if I am at home or not he still with me every day. It's like he comes and goes all day. I just would like to know if any body had this happen to them? Also I talked to a psychic medium an she confirmed what I was saying with out me saying it. She said he comes by the bed every night to watch over me in to protect me. My boyfriend has not really talked to me yet I just think he doesn't know how yet.
