It may be unconvincing to tell people the world they think they perceive isn't real. This approach may be construed as your judgment. If you've done this, you may have discovered how everyone doesn't agree. When you're ready to learn more about life in this world and other dimensions, you will naturally attract people who offer much to teach you. As they say, 'when the pupil is ready, teachers will appear.'
As you learn, digest and apply information you absorb, you will find you sense you're being passed from teacher to teacher. As you're ready to expand your horizons, new people will enter your life in a timely fashion. As you stay open to possibilities, you will grasp how an idea or thought is the same in any language. Only the words or gestures used to express it will differ. You can begin to realize thoughts are the universal form of communication. How you transmit thoughts can also evolve.
If you grow to see your physical body as a vehicle, then you can grow to understand that your consciousness can also travel and communicate without your body. Its not so far-fetched. After all, as someone watches you sleep, your mind is succeeding in convincing you that you are in a dreamworld. You will be receptive to whatever mental states and visions you're ready to handle. How do you feel right now?
As your faith in your intuition strengthens, you'll sense you're on the right path as a teacher. You help yourself and other people who benefit from sharing your journey.
