Had two Dreams of my Dead Nan

The First Dream i had Was that throughout the dream a bell could be heard, but i couldnt find it. i was in various of places i didnt regonise.

at the end of the dream the bell was from a phone ringing in my old house which was unplugged . i answered it and said hello then my nan said hello do you miss me i miss you, wish i could show my self to you she went all echoed n i woke up, very fast heart beat and sweating

And the second dream was

she was in the hospital room and calling me in, she had people standing round her i did not regonise and she was see thru. she kept saying come in dont be scared. i was stone cold.
throught out my dream she kept appearing next to me, and right at the end of the dream we was talking about both my exs,both by name one i split up with in 2003 and one in 2008. the one i split with in 2008 she was talking about more, she told me what he was up to at that moment in time (he was sleeping) and that me and him will be together very soon. me and him havent spoken since 2009.
(but i have asked out loud to be reunited with him) and when me and my nan was talking i was in my old bedroom in my old house. she never saw the new house or knew that we moved as she passed before i did.
then she vanished

Do these dreams mean anything?
