In modern cosmology, it is controversial whether the existence of human consciousness can be used as evidence to support the hypothesis that many parallel universes are actualized. In this paper, we want to explore the nature of self-consciousness information that I am awake now. Consider the following experiment participating Al and Bob. We throw a fair coin on Sunday. If the coin lands heads we wake up just one of Al and Bob on Monday. If the coin lands tails we wake up both of Al and Bob. On Monday, at least one of Al and Bob will wake up, to what degree ought they believe that the outcome of the coin toss is heads? We will argue that the correct answer to this question is 1/3. To this end, we will argue the awakened person's information that "I am awake" is given to himself through a random procedure.
