dreams 061309 my apartment

I'm just arriving at my apartment. My Grandma, who lives next door, has locked herself out of her apartment. She wants me to open my backdoor to a common porch so she can get in her place. [confusing that opening my backdoor lets her in her apartment, parallel universe, but then this is a dream] I unbolt the lock to the door. We go out on the porch. Her friends are there. We sit and visit. She can now get in her apartment next door through her backdoor.
