This dream could have several interpretations. The coldness of the hug might symbolize emotional distance or unresolved feelings related to the person who hugged you. It could suggest that while there may be a connection, there is also a sense of discomfort or fear associated with it.

The act of scratching your neck could represent anxiety or stress that you are currently experiencing in your waking life. Neck scratches in dreams can sometimes indicate vulnerability, as the neck is a sensitive area. Your decision to wake yourself up may reflect a desire to escape from this anxiety or to regain control over your emotions.

Consider reflecting on your current relationships and any situations that might be causing you discomfort. This dream may be prompting you to address these feelings rather than avoiding them.
