Dreaming that you are eight years old represents the memories you had during that time in your life. Whatever factors, life circumstances or qualities were dominant during that period of your life, could be trying to come through to you in your dream. Dreaming of the number eight could represent ideas about infinity or infinite possibilities – 8 turned sideways is the symbol for infinity. The symbol may be attempting to convey your limitless nature and your potential to do great works in your lifetime.
