What do you think this dream means?

I dreamed that my mom went into a large building with an orchestra and a movie theater. She was wearing a beautiful white dress and was inviting me into the orchestra hall. I walked up to the door with her and the man in front taking the tickets said something to her and myself that I can't remember before she walked away and I did, too. This happened again, and then I walked out of the ornate white building with gold trim on everything and left. The floors were dark marble.

After that, I dreamed that I, my cousin, and she were all looking at animals in square cages lining walls from floor to ceiling creating more aisles with the backs of the walls being plywood. There were several walls in the same room with an aisle on the right and I believe right center where one could walk from one aisle to the other through. The room was dark, and each animal cage was lit by a single bright light in a corner of the cage. There were aquariums, too.

One animal was a black octopus. It was my mom! My mom had become a black octopus which sat in the back left corner of its aquarium under a black light, the UV lights that glow purple. I could see like a hologram superimposed behind it her laying in a hospital bed. My cousin and I looked on wondering if she would die or live. She lived. Then I left the animal room after looking at the other creatures in their cages including a bird and a black reptile.

(See the first answer. I continue the dream there.)
