If you dream about yourself being kidnapped, it means you are worried and distrustful of people and environments. This can happen when you have moved to a new place and you are unsure about its environment.
This dream about kidnapping can be a warning. It reminds you to be mindful of risks and not to show off material possessions, because it incites envy and forceful response from people who are at ease with committing crime. You need to protect yourself by reducing your exposure to harm. In another level of understanding, you need to reduce your showy nature. Avoid excessive show of extravagance.
Dreaming of kidnapping and potential loss of wealth paying a ransom, are reminders to save money and exercise thrifty habits.
