Seeing foam in a dream is often an indication that you are experiencing temporary delight. The most common interpretation for this type of dream is that the dreamer will enjoy an abundant life for a temporary period of time.
It can also mean that the person may be getting ahead of themselves or they may have too many things to do and not enough time to do them.
Foam in a dream signifies disappointment. It is a symbol for deflated expectation, anger, or frustration. You may feel like that one of your aspirations will never come true or that you’re not living up to your potential.
