Recurring dreams of my girlfriends dead grandad

Hi guys,

I have been having a couple of dreams which involve my girlfriends grandad who passed away last january. Although I never actually knew him very well, we did talk when me and my girlfriend came to visit him and her nan. We had only been going out for about 6 months when I met him, his name was Brian and he had recently been given 3 months to live when he was diagnosed with Lung cancer. He was never particularly healthy looking, but after a month or too had passed, he was the shadow of the man he used to be. His arms and legs as thin as a rake, gaunt face and brittle. Sadly he passed away in the january, and throughout his deterioration we did our best to keep her nan busy and help out around the house etc.

Roll forward to a couple of months ago. I was staying at my girlfriends house, and as her dad doesn't agree with us staying in the same room together, I stay in the box room. I had slept in there loads of times, nothing ever happened. I drift off to sleep and find myself with the girlfriend at her aunts house, she is there with her current boyfriend. The music is going and we are laughing, my girlfriend, aunt and the boyfriend are on the sofa, and I am on my own sofa across the room. A shadow appears on the rug in front of us. Despite all being near, they don't seem to acknowledge what has happened, on second glance the shadow turns into a man, crouched down. He gets up, at this point I am panicing, scared and frightened - this man has died, he can't be there - can he? It was Brian, looking really healthy and glowing. He tries to talk but it is like he is restricted, he manages to say "I'm alright, i'm alright. I'm with my mum!". Suddenly the ground vibrates and there is an awful loud rumbling sound - very much like an earthquake. Boom, I wake up. In tears, I was coming to terms with what had just happened. The box room was ice cold, despite there being two radiators in the room. It took me 2 hours to get to sleep again, by this point it was 5am, and I was in work for 7!

Another month goes by, I had slept in the room for countless nights with no problems. I go to sleep like ever other night, and find myself at a friends house. I don't actually recognise him, but he has a name which he responded to. We decide to go upstairs to watch TV and play on the laptop, I decided to sit on the bed watching television as he sits at the computer desk. As I glance away from the tv, I see a figure in the corner sitting in the dark on a chair. My eyes water up, as he gets up out of the chair I recognise the face. It was Brian, looking the same as I saw him the last time in the dream. I had realised what was happening, and in my mind I had gathered that the scenario of being in the house was all irelevent and that it was this moment my dream had been waiting for. He got out of the chair and made his way into the yound teen in sitting at the computer. Brian placed his arm around him and told him "You must do it this way, you must! It is the only way, It is the only way this is going to work". Hearing his voice, reminded me of how he spoke and his accent. I had forgotten what his voice sounded like, until now. Again I was visably distressed, the moment he had got the words out, the vibrations start and the ground shakes. Boom, back awake and in tears. The room now ice cold I can see my breath as I breathe, I decided to try sleeping again, this time with no problems.

Can anyone help me in decifering what these dreams mean, and why am I getting them? I was not massively upset at his passing nor was I directly affected. Is my mind trying to tell me something? Hopefully you guys can help me out,

Thanks
