I stayed at my friends house after a boat ride. every night he would walk like he was possessed to the boat and try and turn it on
The dream may represent a sense of unease or concern about something that your friend is trying to accomplish. The boat ride could be seen as a metaphor for a journey or a goal that your friend is pursuing. The fact that he is walking like he is possessed may indicate that he is very focused and determined in his pursuit, but perhaps to the point of obsession. The fact that he is trying to turn on the boat could represent his desire to make significant progress or achieve a big breakthrough in his life. Alternatively, the dream may reflect your own worries or fears about your friend's ambitions or behavior. You may be concerned about the potential risks or consequences of his actions, or you may feel like he is being too single-minded in his pursuits and neglecting other important aspects of his life or relationships.
