You can not feed this into your computer. Telepathy happens between the sender's and receiver's brain, and because you are "listening"to somebody, you will "hear" it in the first person singular, present tense. But more than that. You are receiving your senders total experience here, his feelings, his joy, his fear. For example, my pet bird had a fright when the cat jumped up to his cage. The bird called me in cold terror. I then telepathically experienced his terror, saw the cat's face and put two and two together.
Because dreams are telepathy in the sleeping state, I actually started out by dream interpretation. (For starters I had background in psychology and what we knew of dream interpretation) The first thing is to memorize your dream. I mean memorize every detail, however insignificant it may seem. Once you are confident you can memorize your dream, start writing them down. You will be surprised how hard that can be. You ommit details (resistance). You forget details (resistance). Once you are confident you can recall and write down your dreams, you can start interpreting them. Dreams come through symbolized. You need to learn to interpret the symbolism.
Took me years.
