Dreams of hugging can often symbolize a need for comfort or connection. In your case, since the person is someone you used to work with, this dream may reflect your feelings about her departure and the changes in your work environment. The act of hugging in the dream suggests that you may be processing feelings of loss or missing the camaraderie you shared, even if you didn't have strong feelings for her.

Falling to the ground while hugging could symbolize a sense of vulnerability or a desire to connect more deeply with someone, perhaps indicating a yearning for closeness in your life. The lingering hug might represent your wish for more time with this person or to hold onto the positive experiences you've had at work.

Feeling lonely after the dream could be a natural response to change, especially if you valued the interactions you had at work. It might be helpful to seek out connections with others or reflect on the positive aspects of your relationships, both past and present. Consider reaching out to friends or engaging in social activities to help alleviate those feelings of loneliness.
