Source: The Great Interpretation of Dreams (Ibn Sirin)
A bell in a dream indicates news or a warning. Its sound indicates fame or scandal. If it is hanging, it indicates a postponed matter.

A bell indicates a hypocritical man or false speech. Hearing it indicates worry and grief.

A bell is interpreted as news. Whoever sees himself hearing it will hear news.
