Dreaming of a cassette tape means hidden truth and unrealized potential. You must not suspend the disbelief once you discover it, instead dive deep into uncovering more. Pay attention to the chorus, the part that repeats is the part that holds the most truth. All the words are there, and you can do anything and everything with it. In your waking hours, write down the words and repeat it yourself to attain great success.
The cassette tape in the dream also symbolizes our subconscious mind and its contents. It is a recording device to keep information and older memories safe.
