The first part of the dream sounds like you have a affinity for the ocean.Looking out over the balcony can be exhilarating. Seeing the ocean like that is awesome. It seems you may take a vacation soon.

The ethnic lady and the wall of water is interesting. She saved your life, but couldn't do anything about the wall of water. She sounds like a psychic. Maybe somebody in your life is going to try to save you, or already has. It could be somebody in your workplace that is helping you, or going to help you.

Do you have any pets? I get the feeling you are worried about the animals. Your mom being there is to reassure you that everything will be alright.
The pet store may represent your life ,and troubles you may be having in life. It's great that you mom and bf are there.They are there to help protect you.

The slaughter house could represent a unsafe place. You find yourself back in the hotel after. That could be the safe place.

Only you can really figure out what your dreams mean. They are intimately
connected to your life. I did my best to help, but I may be wrong about some things. Good luck
