My dad didn't love me anymore and I had to go through many challenges to make him love me again including dressing like a slut. And after he finally liked me again, I wanted to go away from him because I didn't want to fake being someone who I am not for someone else.
Dreams about parental neglect or abandonment can often reflect feelings of insecurity, fear, or rejection. Your dream may symbolize a fear of losing your father's love or approval. The challenge you face in the dream may represent your attempts to regain his attention or affection, even if it means changing yourself in significant ways.
The symbolic act of dressing like a "slut" may represent your desire to be more sexual or alluring, or it may reflect a sense of feeling objectified or valued only for your appearance. This could suggest that you feel pressure to present yourself in a certain way to win your father's love.
Wanting to walk away at the end of the dream suggests that you may have conflicting feelings about the relationship with your father. On one hand, you may feel driven to try to please him and gain his approval, but on the other hand, you may feel disillusioned or frustrated by the fact that you have to be someone you're not to get that approval. It's possible that the dream is urging you to examine your relationships and think about ways you can be true to yourself without giving up important connections.
