To hug someone in a dream means you are welcoming or embracing something into your life. Is it a new attitude or belief? A new regimine? A new person?
If someone is hugging you then ask yourself if you are feeling welcomed in your life.
If someone you don’t know in real life is hugging you, then ask yourself what you need to embrace. An unknown man would suggest you are embracing your male, assertive energy. An unknown female would suggest you are embracing your feminine, creative, nurturing energy.
Hugs are almost always a positive sign that you are feeling closer to someone in waking life or that yu have embraced a new attitude or outlook.
