It is almost traditional

It is almost traditional in many cultures to try to remember one's dreams, and dreamologists will even interpret them for you. This all borders close to the realm of superstition and is far less desirable for spiritual growth than other more pragmatic types of practices. A beginner on the path, or even one in the intermediate phase, should endeavor to forget dreams and strengthen the fibers of the mind and psyche through daily sadhana. There is actually a time, on the yoga marga, after the charya and kriya margas have been well mastered and passed through, that the remembrance of one's dreams is beneficial and fruitful, but this would only be between the guru and the shishya. - from Satguru Sivaya Subramuniyaswami
