The phrase "I don't know where we are going now" generally expresses uncertainty or lack of clarity about the current direction or future path. It can be used literally, when someone is unsure about their physical destination, or metaphorically, to indicate uncertainty about the next steps in a situation or life in general. This phrase also appears in the song "Dakota" by Stereophonics, where it reflects an emotional state of uncertainty and reflection about past experiences and the future.
In everyday language, saying "I don't know where we are going now" typically means a moment of doubt or indecision about what comes next, either in a literal journey or a figurative sense regarding plans or decisions.
Thus, it conveys a natural feeling of not having a clear path forward at the moment.
