A dream that scares me

I have this friend that lives in mississauga (he's a senior - grandpa joe), I've known him ever since I was little and he has always looked at me as his own grandaughter. Well I live in scarborough now... But use to live around his complex in missauga....

I had a dream that I still lived there, and I was walking home from my old school, right when I spot his wife talking on the phone through the window... I was drawn to ring their doorbell. His wife (who I call grandma irean) looked so old. (havent seen them for almot 3yrs) anyways I rang the doorbell and grandma irean welcomed me with open arms, while saying "omg look at you... So big... I almost didnt reconize you!!" we were talking for quite a while at her breakfast table (house seemed to look just the way I last remembered) but than she dissapeared!! I went looking for her and saw my friend (susan, that lives in scarborough) with grandma irean and she was trying on a dress. She invited me to come a long with her, but I shook my head, because I was drawn to the living room where I saw grandpa joe. And omg he was sitting on the sofa and he looked so old... I softly said "grandpa joe" and he called to me... And told me to come over. I swear I felt like I was 5 again, because he lifted me up and sat me on his lap. I then looked at him and said I was srry for not coming to see him earlier. He then hugged me and said it was okay, and that he wants me to noe that my family and I are always welcome to see him and that he loves us all. I slowly then pulled away to look at him again to say I loved him... And began to cry! He then said that he noes I love him and told me not to cry and hugged me harder. As I sobbed on his shoulder. I heared a knock...and it grewlouder and louder!! Than I noticed I was left sitting on the sofa alone!! Grandpa joe was gone!! I heared my mom yell at me to wake up as she was knocking on my bedroom door!! I woke up and I was there lying on my bed crying!!

What does this dream mean? Someone please tell me!! Tho it was a dream I had last week it still bugs me!! It bugs me because grandpa joe is real old now... And grandma irean has called a several times to tell my family and I about some operations that he had one year she called about a kidney transplant and I forgot what the other was but I just noe... He has a several health problem now that he's getting older.

I'd like to call them... But I'm really scared if this dream really ment something (if you know what I mean.)

maybe becasue they are geting older and as you said your grandpa s gettin quite old and has health problems and that maybe your worried that they may die (disapear)
