Water that has stopped, which is why the image is read for things held in place, whether that feels like safety or like being stuck.
Begin with the bedroom, because this is one of the images that regularly has a physical cause. A cold room, a kicked-off duvet or a window left open in February pushes cold into sleep, and a scene gets built around the sensation. Once that is accounted for, the traditional reading concerns stillness: ice is water that has stopped, and the picture is taken as something in your life held in place, whether that feels like safety or like being stuck fast.
Half the vocabulary of emotion is already temperature. People go cold on an idea, freeze somebody out, warm to a stranger. Dreams take those expressions at face value, which is why an argument that has settled into silence turns up overnight as a frozen lake. The interpretation follows the emotional language rather than the weather report.
Somebody who grew up walking on frozen lakes and somebody who has never watched standing water freeze are not dreaming the same substance at all. For the first, ice is a surface with rules, tested and trusted every winter. For the second it is an exotic hazard glimpsed on television. Your own experience of the stuff sets the tone before any interpretation gets a look in.
