I woke up early this morning but fell asleep for an hour. During this hour I dreamed I was in a superstore. I was buying things, the most clear thing I can recall buying is sushi, I walk around for a while, I see a man eating sushi off from a abandoned shopping cart. As I proceed further, I realize my shopping cart has grown 4 meters tall and out of my reach. I just leave my shopping cart and head out of the store. As I leave, I jump past security, 1 man (black I think) rushes out after me. I ask him is hes accusing me of stealing. He tells me to empty my pockets, as I do, I recall taking out 2 pens and a few other objects. He then tells me to follow him, we go through these big doors outside the store, up some stairs. I am brought to what I think is a gym filled with athletics students and teachers. Being frustrated I am brought here for doing nothing wrong. I quickly start jumping around people, and even jumping backwards and working through the crowd of people. Everyone is impressed by my abilities and reflexes, I then proceed to head out the door, but I am stopped, they want me to join their team or something, telling me I would be a great addition to their team. I tell them I am simply here for ........ I then proceed to a room, tiny one I think. I get on my laptop and 4 kids show up, they look around the age of 15. They've come to applaud me on joining their school (or team). One of the kids I can recall as being my god-sister, Luciana, but she quickly leaves. The other 3 kids are 2 girls and 1 dorky boy, with round glasses. The dream ends as I wake up to a ringing phone, it's my sister.

Background info:

I live in Canada, but I am currently vacationing in South America(birthplace).
I like sushi, but get sick of it after eating a lot.
I have recently meet my god-sister after 14 years, since she was 3, while vacationing.
It seems the superstore matches descriptions of a superstore in Canada, while the school/gym part matches something from South America.
