This is interesting - the pregnancy aspect of your dream points to a deep psychological desire to express your feminine side, a side which has been supressed due to social unnacceptance. Most men who dream about pregnancy are keen to come out of the closet and express their femininity on a more permanent basis but are too afraid to show it. However, this is further enhanced by the fraternisation with criminals who weren't criminals - basically masquerading - those in hiding. Being chased by men, well, that hardly needs too much of an explanation. The famous psychologist Alber Schteiner has linked these basic subconscious elements as, and I quote, "The oft mentioned male pregnancy harks to strong homosexual tendencies often masked by the wrappings of more macho paraphenalia (cars, bikes and trucks primarily) and offers cause for discussion with a psychologist or analyst". On impersonation and masquerading he says, "Hiding behind masks, masquerading as someone or something else, particularly those in authority (police, army or other armed forces) signifies a fear of revealing a true identity or desire. If, however, the individual is surrounded by, or is in the company of, those masquerading as someone/something else then another aspect of desire is revealed. As in chapter 2 the subject is expressing a subconscious need to express a homosexual side of their personality hitherto supressed."
