Back in the house where I grew up

I had a dream that my older sister, D had driven up from where she lives to visit me. We went to some kind of park that had lots of huge stone structures. Some were just huge stone columns surrounding a cement area. Nearby were rest area buildings. Inside at least 1 of the buildings toilets had overflowed onto the whole area & I had somehow managed to step in the water b/4 realizing where it was coming from. I was disgusted & took my shoes & socks off so I could wash my feet in a nearby area. I figured I'd just take my shoes & socks home & wash them. Suddenly D said she felt real sick & wanted to go home. I told her maybe I should take her to a hospital, she said no, just home. Just as I was going to rinse my feet real quick, she started vomiting. So we got into the car & went home. 'Cept "home" was the house where we grew up. We went in the side door & I went downstairs to put my shoes & socks in the washer. D was still vomiting, but said she'd b ok. I think she figured it was food poisoning. So I was going to get some sheets & a blanket & put them on the couch in the basement so she could lay down & watch TV if she wanted to when the phone rang. I went up the stairs where there happened to be a phone at the top of the stairs near the door. It was warm out & I'd left the door open. I answered & it was a female looking for me, but she pronounced my last name incorrectly. When I corrected her, she said she must have the wrong # & asked if I knew any neighbors by that name. I told her no it was me she was looking for. She said she had a package for the person, but she'd look elsewhere & hung up on me. I dialed *69 & got the phone # she called from & dialed it back. It was a package delivery place. A male answered & I told him what had happened. He transferred me back to the female I'd spoken to, I convinced her I was who she was looking for & she said she'd have the package sent to me. Then I woke up.
