Have you been feeling lonely or looking for a partner?
Thanks for the additional information.
I believe that the dogs in your dream may be symbolizing people in your life or an idea of a person. You may be feeling lonely and subconsciously missing affection from a partner and therefore having these passionate dreams with the dog.
Same as years ago with the professional situation when the dog was observing you and your were uncomfortable can be a representation of any insecurity you may have felt in that professional situation. However, when you saw him again this time you were more secure and observing him and accepted him into your space while also looking for affection.
I hope this helped! Please let me know if I can be of further help.
Please request him.
Mrs. Sandman may be less often on this site than you are hoping for. I've worked on the same dreams as she on many occasions; and sometimes the customer prefers her interpretations to mine, sometimes mine. My take on the 3 dreams you've briefly described presents an alternative to jenhelant for what the dog(s) represent--your instinctual self, that is always looking after you with great loyalty. The business associate that triggered two of the dreams awakened both a guardedness and an unconscious identification to him as a masculine counterpart, not necessarily a romantic or business partner, but a symbol of the masculine side of yourself (see C. G. Jung "Animus" in wikipedia). Women who live and work by themselves (including artistic work as well as business) may unconsciously envision themselves as partnered with a man who furnishes capabilities that their feminine ego is gaining comfort with. Your aloneness may be a stimulus to your creativity and appreciation of the world around you--as evidenced in your careful attention to the setting in which you want to establish a new home.
If you want to pursue these dreams with me you can respond. If not, then Mrs. Sandman will have more interpretation to eliminate and you will have more responses to choose between.
It's Mrs. Sandman, unless there's somebody new named Sandman.
