The meaning of pebble in dream | Dream Interpretation
1. Hidden strength.
2. Difﬁcult times, troubles.
3. Harsh judgments, often not justiﬁable (as in “people who live in glass houses should not throw stones”).
Dreams of a pebble are a message to you telling you to pay attention to the little things in life and that there is no such thing as a neutral action. Your dream is showing you that every action you take is like a pebble tossed into a lake that causes a ripple effect of change. See Rock.
