When dreaming of a bus it could represent a church or teaching ministry.

Positive: Dreaming of a bus may represent unity in a group or one’s ministry. It could represent learning or submitting to the church. Dreaming of a passenger or tour bus could represent sojourners which mean to stay or dwell in one’s ministry or personal life.

Negative: Dreaming of a bus being empty could indicate a church split.

(Hebrews 11:9).
