We have proved through finger reading experiments on sacred words such as Buddha, Bodhisattva, Jesus, etc., that the extraordinary phenomena such as bright light, bright person, laughter, Cross, etc., observed on the inner screen of the brain of the person with exceptional human function originated not from his hallucination but from the external information field (spiritual world) which transcends the four dimensional space-time material world. Our further experiments demonstrated that the information field is filled with high intelligent information (spirits) that occasionally participated in our finger reading experiments and resulted in chaotic consequence. Therefore, the degree with which the spirits took part in the experiments became a significant variable. However, we could utilize this phenomenon to communicate with the spirits in the finger reading experiment by changing the wards to a lengthy question. During the entire experiment, the person with exceptional human ability didn't see anything or any word on her inner screen; therefore, her answers came not from her consciousness or sub-consciousness, but from the spirit in the information field. From the dialogue, we obtained a deeper understanding of the structure and characteristics of the space-time in the universe, space travel, extra-terrestrial civilization, and information field.
