dead-end dream

I had a dream this morning. My uncle has a house down at the shore; its built on a man-made, three-pronged peninsula that sticks out into Barnegat Bay. There is a road that goes down each "prong," and his house is on the center one. So, in my dream, I was bicycling with some people, supposedly friends of mine, but I don't remember who they were. We got to the crossroad where each prong joins the main road. Some people went left, some went right, and some went straight. I waited at the crossroad, because I knew each one ended in a dead end, and I knew they'd have to come back, so I waited for them. When I woke up, I thought, Yeah, that's my personality. Practical and precise. If I know a given option is going to land me in a dead-end, I won't waste my time on it. But then I started thinking more about it. Surely the other people must have known also that it ended in a dead-end. At least, the ones that went down the center road would have known- they could see the end. So why did they do it when they knew the road would end? It must have been because they enjoyed it. They were getting something meaningful out of the path they chose. What if my methods aren't as practical as I think? What if I'm so afraid of hitting a dead-end in my road, that I am more interested in sitting at the crossroads waiting for everyone to come back and tell me about it, instead of going out and experiencing it for myself? What if this dream is making me think too much?
