I was playing basketball but there were darts beign thrown at us while we played. Basically, everyone was running around and had to dodge the darts but still play, including myself. At one point in the dream, I had the ball thrown to me and suddenly I saw a dart heading towards me also and the dream ended.
The darts may represent others' looking at you and their opinion of you. I think that you feel like you're being watched when you do things such as play basketball, which may be equivalent to daily life if you play sports or love sports. You may be putting too much importance on what other think about you rather than focusing on what you have to do.
I think that this dream can be taken more literally or symbolically. You may be nervous about a basketball game or sport event and you feel like a lot is expected of you. Or, the darts and basketball coming at you at the same time is symbolic of you having a lot going on in your life and you need to chose one over the other; catching the basketball or dodging the dart.
