Guenevere, Genevieve, or Gwendolyn the mermaid
I dreamed that Liz and I swam in an outdoor pool at Rockefeller Center. She had a pet mermaid which looked like a fish. The mermaid lived there at the Center, sort of like an outdoor dog. One day the water turned cold and she froze in the pool. Not yet understanding we picked her up from her perch as she 'slept'. We released her into the open water so she could frolic as usual... but instead she drifted inanimately to the pool's floor. When I caught and collected her cold little body, felt like a doll, a stiff squeaky toy, or a chicken breast.
