To dream that you are looking at an advertisement denotes that you should take great care to listen to a subliminal idea. The subject matter in the ad is indicative of an aspect of youself that wishes to be noticed or accepted. If someone you know is advertising themselves, then this symbolizes knowledge or expertise they possess that can aid you with a certain task. You should learn to accept assistance from others rather than trying to tackle a difficult problem on your own.
To dream that you are putting out an advertisement implies that you need to apply more effort in order to attain your desired end result.
