To dream that you are bowling represents the strikes, hits, and misses in your life. If you are bowling a bad game, then you may be expressing some regrets. If you are bowling strike after strike, then it suggests that you are on your way toward a successful future. The dream may also be a pun on your striking performance and/or stellar ability.
To dream that you bowl a gutter ball suggests that you are stuck in a rut and need to make some changes of where your life is headed.
Alternatively, bowling and bowling alleys may also be a metaphor for sexual conquest. Consider the sexual innuendos that are at play in the bowling alley. The pins and bowling balls can be viewed as masculine symbols. The pin deck is symbolic of the womb or vagina (as is with any dark receptacle like caves, bowls, containers, etc.).
