Early this morning i had a dream of my deceased great grandmother, which by the way is my adopted mother. ....?

My dream had myself, my gma, my twin and my godfather and not to mention my exboyfriend...mind you my exboyfriend didnt get a chance to meet her bcause she's been deceased for over 2 years...anyway...we were taken a tour in this old white house that was a shape of an L...to make the story short...i went outside to my cell out of the car when a van with 3 woman pulled up older woman in like their mid 60's...in my dream we all knew my great grandmother (mom) was deceased...i see this old woman staring out the penger window...i try to focus my eyes because i swore that i saw my (mom)...her faced changed in front of my eyes like she aged within seconds...i gues because i couldn't recognize the younger her...her faced changed to how she used to be before she ped away....anyway, she gets out of the car, i'm in complete shock because its totaly impossible to see the one person you cherished you're whole life be right in front of you....sad part was she didn't know who i was...when she stepped out of the van...i asked...Mom!...she looked at me and said excuse me but in spanish...and i called her by her name...and said yes i am adela...i walked away....went back into the house my family was like wat happened ur white like you saw something very disturbing...i studdered i couldnt even speak. i just saw mom outside. and they r like what the heck freaking out basically...and my ex was so i'm finally gonna get to meet her he asked in a confused manner... my mom walked into the house and looked at everyone and made her way into this beautiful seat...we were all starring and we couldnt believe it...then she looked straight at me and said can you go get me my wallet i forgot something in there so i go and her friend that was in the van handed it to me ...and she tells me "you're being watched over."..i looked at her weird cuz she creeped me out when she said that. As i was walking back to give the wallet to my mom, i found this envelope with a sticker heart and writing..it was a valentine card written by a child..i was reading it and as i finished reading it...it ended with Love Joanna...my name is Joanna...so i rush back and i asked her how did you get this note, where did you get this note i yelled..my ex was like wat is the matter....i kneeled down and look at here into her eyes...and i begged her to remember me....she looked at my ex bf and said to him in spanish..el amor duele (Love hurts)..estar juntos es todo lo rason para vivir ( to be together is all the reason you need to live)...and she looked at me and said te quiero muncho mi amor pequena...( i love you so much my little girl) and my dream went into this bright and white blank background and i woke up.....I'm just so confused and want to know why i dreamt this dream...what does it mean when you dream of a deceased mother and your ex boyfriend together when they actually never met....i need an interpretation...
