Psychologically: In the dream the dreaming is still reached from all real noises. Therefore, the hearing can be released in the dream by the still perceived noises, but also by illness and exhaustion. As a dream symbol many noises point to the fact that the dreaming of others is too very influenceable. If he listens in secretly, this can be a picture for his curiosity or also for his mistrust. If he sees to hear listening in ears without noises in the dream, this means that he deals too much with his own person, so too much in himself hineinhorcht. (See also Deaf of)
