Recurring dreams about my beloved dog being lost then found......

I am having recurring dreams where my darling little dog is lost when I am out walking her.... in my dream we move house and I think she has run off to return to our old home. I go to search for her and she isn't there.... nothing is the same without her.... after about a week she turns up. I have many changes going on in my life at present. My daughter is going off to start Uni and my husband is moving away to work... I feel this dream is expressing my fear of being alone and every one ' leaving ' . I am so very proud of both my daughter and my husband..... will visit my hubby each week and stay and he will be home weekends. My daughter has does so well to get into Uni and is not going forever! I guess it's all big changes at the same time ..? These dreams are upsetting and making me feel worse...... please advise! Many thanks Tweet
