To dream of things that are unisex represents some area of your life that is predominantly focused on compatibility, fitting in, or ease of use. Function before all appearances. Some area of your life that is “general” or widely accepted. More of a concern about how something is used than how it feels.
Negatively, unisex may reflect too much concern with keeping everyone happy.
Example: A man dreamed of seeing the word “UNISEX” in big letters. In waking life he was beginning to realize success in business because he decided to make his website more mobile compatible instead of focusing on beautiful design.
