Dear DazedandConfused254,
I have had dreams like that too although I am generally quite happy that I am single. The human brain is so mysterious and seems to have a mind of its own. Since you are a very complex human being, I wouldn't really have any clue about why you are having these dreams. If there is some way to "control" what dreams come to one during sleep, I don't know. I am so sorry that your life is being disrupted by your dreams.
Sincerely yours, Yao Wen
