Psychic? past lives? just read book "many masters many lives"?

I just read many masters many lives and it has got my mind going crazy. it talks about how when you die you keep being reborn into new lives until you have learned everything that you need to. could you imagine if this was real? do you believe that when you die you are reborn into a new life and you make up the karma from past lives? they said that the people in your life right now more than likely were in your past lives also as different people. what do you think of all this? have you had an experience where you remember part of a past life or was hypnotized and discovered this?
