It was a dream that I had:

In the dream I was trapped in a bird cage. She was alone in the room, I remember that it was dark and it felt very cold, you could only see a small light that shone on me all the time as if it were a lamp that was broken and went from side to side. I wasn't able to get out, I felt trapped and I just screamed and screamed but no one could hear me and I hit with all my strength. It was like there was a monster inside me that just wanted out to be free. Finally, after so much hitting, I managed to free myself, I broke the bars and managed to get out and I saw the light but I couldn't go towards it because I fell exhausted.
