I need help badly please

I went close to it and checked what it was. To my shock it indeed was a UFO. suddenly the door opened and I was sucked into it. I felt as if my head was rotating. Inside the UFO it smelled like rotting meat. It smelled so bad that i felt dizzy and i fainted. I woke up when i heard my dog Jack bark. i opened my eyes to find my self surrounded by strange people. the had different number of eyes. Some had two eyes while some had three. They skin was bluish green in colour and smell like fish. They took me to their leader. He was sitting on a fish scale covered throne. He asked me who i am. I was shocked that i could understand his language. i claimed that they were intruders and was in my planet earth. He laughed and told me that i was in there planet, polybroke. I did look around, he was right. even before i could say anything he asked his pawns to execute me. The i screamed in terror only to find myself lyning on my bed. My dog gave me a shocking look.
