If in your dream you are doing something that looks like a gel in your hands, then in real life you will be engaged in a business that for you will not seem to be completely successful. At least, you will constantly doubt it and will not be sure of success until the very last moment. If you dreamed to smear a gel on your head or just apply it to your hair, this tells of your desire to be to others around someone else, a different person than you are in reality.
