It could mean that the person's thoughts or mental state is like an animal story, full of wild, instinctive or untamed ideas. Maybe it's a creative way of expressing that their mind is filled with stories related to animals, like adventures of animals in the wild.
The album cover of 'My Head Is an Animal' is quite unique. It might represent the wild and untamed nature of the music within. Maybe it's a metaphor for the band's creative minds being like animals, free and full of primal energy.
Sure. Let's say a person reads a story about a migrating bird. Later, when they are facing a difficult decision in life, like whether to move to a new city for a job opportunity. Their head becomes that animal story. They think about how the bird overcomes long distances, faces various challenges during the migration, and they draw inspiration from it. They might think 'just as the bird has the courage to fly to a new place, I should have the courage to move for this job'.
When I was skiing last winter, I was going down a slope at a fairly high speed. I got distracted by the beautiful scenery around me. Before I knew it, I crashed into a signpost at the side of the slope. My head hit it with a bang. I was dazed for a bit, and my goggles got knocked off. Fortunately, the ski patrol was nearby. They helped me up and made sure I was okay. I had a big bruise on my forehead for days after that.
One day at school, during a recess, we were playing tag. I was running away from a friend who was 'it'. I turned a corner too quickly and collided with a pole. My head made a loud thud when it hit the pole. All my friends stopped playing and gathered around me. I felt dizzy and nauseous. The school nurse was called, and she checked me out. I had a minor concussion, so I had to rest for a few days. It taught me to be more careful while running around.
The story I like is about a group of dolphins. They lived in the ocean. One of the dolphins got injured by a fishing net. The other dolphins didn't abandon it. Instead, they helped it swim to the surface to breathe and led it to a place where some humans were helping marine animals. The humans removed the net carefully. The dolphins were so grateful and swam away happily.
