Odd dream. Thoughts?

A little background: my grandparents used to own a small apartment house that had 2 floors & 4 small apartments. They are gone like 30 years now.

Anyway, I was young & single and my family went broke or something and I needed to get an apartment. 2 friends (well, actually 1 cousin & 1 tv show character) were also looking for an apt. and we decided to get one together.

I didn't know if my grandparents would be selling the house but I get a call from my mom that they're looking to rent the apartments (all empty except the one they live in).

So I tell my friends and ask my grandmother about renting the 3rd floor apartment, and she says yes and offers it to me for free. I want to pay her but she says we can use the money to help fix up the house (which is really getting ratty looking).

So me and my 2 dream friends go up to the 3rd floor (which did not exist in this house in reality) and the apartment is like a shopping mall that's been closed down or something. We're excited about how big it is and unique and how we can decorate it, and we start exploring it.

Oddly, people are living on the other side of it, it empties out into a different entrance. I argue my grandparents own it, they don't want to leave, I tell them to stay in their part and we'll stay in ours (and my friends and I agree to just close off the section) then we go back to getting excited and talking about how cool it will be to live here and who's room will be where and such until I wake up.
