Have you ever suddenly felt that someone you know was in trouble ― and he was? Have you ever dreamed something that came true later? Maybe you have ESP.

ESP stands for Extra Sensory Perception. It may be called a sixth sense. It seems to let people know about events before they happen, or events that are happening some distance away.

Here is an example: A woman was doing washing. Suddenly she shouted, “My father is dead! I saw him sitting in the chair!” Just then, a telephone came. The woman’s father had died of a heart illness. He died sitting in a chair.

There are thousands of stories like this on record. Scientists are studying them to find out what is behind these strange mental messages. Here’s another example —— one of hundreds of dreams that have come true.

A man dreamed he was walking along a road when a horse and carriage came by. The driver said, “There’s room for one more.” The man felt the driver was Death, so he ran away. The next day the man was getting on a crowded bus. The bus driver said, “There’s room for one more”. Then the man saw the driver’s face was the same face he had seen in the dream. He wouldn’t get on the bus. As the bus drove off, it crashed and burst into fires. Everyone was killed!

Some people say stories like these are lies or coincidences. Others say that are ESP in true, from studies of ESP, we may some day learn more about the human mind.
