Rear Ended 
To dream of getting rear ended represents a problem from your past coming forward to cause new issues.
To be rear ended in a dream may also symbolize someone breaking your trust, such as an unexpected stab in the back.
Accelerator
An accelerator, gas pedal, or throttle on a boat/airplane, can imply that you have the ability to attain a goal without the assistance of others. However, if the accelerator is jammed or broken and you lost control of it, the dream may be cautioning you against acquiring an addiction or dependency that may have a negative influence on your life.
Pandora's Box
To dream of Pandora's Box suggests a belief that you are dangerous or evil. A toxic belief system may be at play. You could be protecting yourself against intimacy because you may hurt your loved ones.
To open Pandora's box is a strong indication that you may need to seek help in opening your heart and may, in fact, be ready to do so.
