I had a dream that it was my sweet 16, I opened a gift and it was a cell phone, I thanked my parents and took it to my room to charge it. My dad comes in my room with this guy (I'll call him Mark, and I do know him) my dad is yelling at him and than says to me that he raped me and I'm like "No he didn't" than Mark's dad comes in and starts fighting with my dad; I look on the floor and there's this snake slithering around the room
you may be insucure with this "mark". the phone is a interesting thing because usualy phones are a form of self expression or it could be your need to get out of a stressful time of your life. the snake now there is a good topic. historicly snakes have taken different meanings from healing to invirtue. i might mean you have some emotional scars. or the snake could be used in the way of deciet (this being most common) snakes have a way of decieving people into doing this in dreams they normaly would not do. have you ever heard of the Illuminati one of their symbols is a snake. the fight of yours an d"marks" dad may mean some real life tension in your area. now this "mark" may be a guy you have feelings for. or you are dating him.or you may be in another relationship and are thinking of him of what life could be. now rape is another odd thing. i've found that alot of women who dream of being raped are either submissive or are genuinly afriad of being raped.
Based on this and your dream about the baby turning into a dog it seems like you have issues regarding your dad possibly not approving of guys that you like and him not wanting men to be close to you (emotionally or sexually).
Well if you don't really like anyone, then the rape in your dream could be about you feeling like you are being "forced" to have a relationship when unconsciously you feel that you aren't totally ready.
