Snehk's Dreamlands

I was in my house. With my pal we opened up my laptop, to see what's broken inside. After checking that everything is right, I tried to close it, but I've got one part left, and I didn't knew where it was. We decided to leave it for now and go somewhere. I opened the door to my room, and saw that there was a city on the other side. Streets were crowded, and there was a weird restaurant without a wall. I saw that my teacher is sitting there. She said "I wonder what he's doing there." when she saw me. I started to make random exercises, just so she won't disturb me.
