Crash Test Dummy
To dream of a crash test dummy represents an aspect of yourself that fails or takes a fall for someone else. You or someone else that expendable. You or someone else that can be used without any regard. Doing all the hard or dangerous work for someone else with nothing in return.
Example: A man dreamed of seeing a crash test dummy. In waking life he was using a competitors business model with plans to put him out of business after he finished building it.
