Another crazy dream I can;t figure out, please help me!?

I dreamed that I was back in the neighborhood I grew up in. I was there as an adult, my sister was there as a teenager. (when she was thin). It was a sunny day, and there were people sitting on the grass everywhere around us enjoying the day. My daughter off in the distance with friends. My sister says lets go for a walk, sure I say, I tell my daughter, and we go. While walking, and chatting we discover we are at a dead end. I want to turn back, but my sister opens the door to someone's home then enters it. I whisper...WHAT are you doing???? She does not answer, and starts to snoop through the home. she says..NOBODY is here.. We go down some stairs, and there is a Cocker Spaniel. It is wagging its tail,and seems happy to see us. After a bit, and I am clearly nervous, my sister continues to snoop. I am at a door at the bottom of the stairs, and all of a sudden...I hear the door upstairs click. Shhhhh...someone is here!!!! I open the door, and see a door down another set of stairs, I grab my sister, and she pulls away. I run down the stairs, waving for her to follow. she finally does. I see a door heading outside. WHAT a relief, but only to find another dead end. No way out except back through this house. I do see a way out, but it is under a porch. There is a broken part of the fence.I tell my sister under there....quick we can get out, and go back through the front again. She takes her time, and I am sooo scared. The people come out of their front door, and are saying where would they go, there is no way out? THE dog comes over under the porch and is wagging his tail at me, the woman yells under there! they are under there!!! I am trying to get my sister to go through the broken part of the fence, but she still stubbornly is preoccupied with herself. AND she is in front of the broken part blocking it off. The family get on their knees and when the woman reaches to grab us, MY fright woke me up! I can not find out what this one means, and it is frustrating me.
