A phone can symbolize communication. For example, if you dream about your partner, and there is a telephone in the dream, it is about communication with your partner. The location of the phone can also be significant. For example, a dream of a broken phone in the bedroom means you need to work on sexual communication with your partner.
A phone can also indicate you are telepathic. Telepathy is where you can read other peoples’ minds. If you have this ability you already know it.
