No, dreaming about an earthquake is not necessarily a bad sign. Dreams can be interpreted in many ways and there is no one definitive interpretation. Some people might interpret dreaming about an earthquake as a sign of upcoming change or upheaval in their life. Others might interpret it as a symbol of feeling overwhelmed or out of control in their waking life. It could also simply be a reflection of anxiety or stress about something going on in your life. Ultimately, it is up to the individual to decide what their dreams mean to them.
