To dream of a flashlight represents examination or questioning of certain issues. You may be trying to understand or “shed light” on the cause of a problem.
It may also symbolize sudden awareness, insight, and the ability to find your way in a difficult or uncertain situation. You are now able to see what the problem is.
Example: A man dreamed of using a flashlight. In waking life he visited a stress councilor at work who helped him shed light on exactly what he was so stressed.
