Dreams involving running, especially in a snowy forest, can symbolize a journey or a search for something in your life, often reflecting feelings of freedom or escape. The white dress you wore might represent purity, innocence, or a new beginning, suggesting that you are exploring new aspects of yourself or your life.

The tall, white-haired man could represent an ideal or a guiding figure in your life. His characteristics—white hair, red eyes, and cold skin—might symbolize a blend of wisdom (often associated with white hair) and danger or intensity (red eyes can evoke strong emotions). His coldness warming up with your body heat suggests a balance between passion and emotional distance, indicating a relationship or desire that may be intense yet somewhat detached.

The act of entering a cabin together might symbolize a safe space or a retreat from the outside world. The intimacy you experienced inside the cabin signifies a deep connection or desire for closeness, but it may also suggest exploring aspects of your sexuality or emotional vulnerabilities.

As the dream transitions to daylight, it may imply a new awareness or realization coming into your life. Waking up at this point could signify a transition from a dream state to reality, prompting reflection on your feelings or desires.

Overall, your dream suggests themes of exploration, desire, intimacy, and perhaps a search for balance in your emotional or romantic life. Consider what these elements mean to you personally and how they might relate to your waking life.
