My dream began at a pet store that resembled a big warehouse.  I was in search of a pet octopus.  I was assisted by a young man who placed a maroon-colored octopus in my arms.  I walked around with it in my arms for a while and decided to set it down for a while.  It started running around, and I chased after it.  Not long into the chase I became frightened and ran from it; here the octopus started chasing me.  The young man who had given me the octopus caught it and again placed it in my arms.  I began walking again and decided to buy the octopus some food, so I asked the octopus what it liked to eat.  The octopus couldn't talk, but we could communicate.  I stopped suddenly in front of a row or clear refrigirators and asked the octopus if it could shock me.  The octopus responded by placing one of his tentacles in my mouth.  I fell to the floor where I lay for a minute; when I arose, the octopus was again placed in my arms.  We headed to the reptile section.  I stopped in front of an aquarium where snakes had tried to escape through the bottom but had suddenly died.  Half of their bodies had managed to taste freedom.  I blinked and suddenly I was in a stranger's driveway.  His garage was open so I walked inside.  His pets were dying, among them a dog, already covered in maggots.  I walked inside and was greated by a young male.  I asked him if I could use his bathroom he said yes and showed me the way.  The inside was covered in blue carpet and there were three steps that led down to the toilet.  I closed my eyes for a second and when I opened them I found myself in a classroom.  The classroom resembled the classrooms in the movie Matilda.  There were only girls inside the classroom, all no older than 13.  They were all waiting in line holding AM/PM cups.  I too was holding one and was told to urinate in it.  There was a table on the right side of the classroom where all the cups were being placed.  I did what I was told and I gave it to my instructor.  She looked inside and said that it was the right color; I didn't understand.  At the end of my dream I realized that the world was ending and the color of my urine was the only way to save the world.  (I am not sure why this was the solution.)  I also realized that the only reason why my urine was the right color was because the octopus had shocked me.
