What is the meaning in a dream of castle

I was at a friend's house, and his parent's bed was in the middle of the house. next to the bed, some stairs lead to an underground animal room. the first room had fish tanks. a bed with fish tanks around it. but it is all crocodiles, sharks and piranhas. the friend threw food at us so that the crocodiles could eat us or the food. in the second room was a kid's play area with what looked like a black lion and a white lion, somehow I ended up in the play area. the entire place was deflating like a jumping castle and the cage to the lions were open as I exited the gate a lion was in front of me as I turned around it grabbed me on my shoulder. then it cut to me being on a highway trying to tell people there was a zombie attack happening. everyone is dying around me. and everything repeated again

I am in a large strange building with many nooks and alcoves, random staircases, etc. It is attached to what looks like an old, battered castle but freshly painted. This stands on a dry, arid hill next to a forest. Within this building are many different people. I meet a young woman with long dark hair and a beautiful smile. We fall in love. We spend time together simply enjoying things. But whenever we try to become intimate, others come and interrupt us. It feels as if this is deliberate. Almost as if we are being hunted.

I dream with Persephone and Hades, they were running around an old castle ruin as mortals, for a long time I didn't knew it was them until they called each others names, they were grieving the fact they couldn't be together.
