Theory:

     When Gulliver woke up he was lying on his back and the sun was in his face. When he tried to get up he found himself unable to sit up or move at all. Terrified and puzzled, he tried to turn his head. He found his arms and legs were securely tied with slender strings on each side and attached to pegs fixed on the ground. His hair, which was long and thick, was similarly tied down. He felt something moving along his body almost up to his chin. To his surprise, he saw a human being not six inches high, with a bow and arrow in his hands, and a quiver at his back. Gulliver later learnt that these creatures were called Lilliputians. Startled by this sight, Gulliver cried out and soon managed to free his left arm. The frightened Lilliputians fired dozens of tiny arrows into his hand, face, and body until he once again lay down calmly. The Lilliputians then built a stage to Gulliver's side that was about a foot and a half tall, upon which an obviously important person stood and made a ten-minute speech to Gulliver in a language he could not understand.
Explanation:
  
When he woke up, he found that he was lying on the ground flat and facing the sun. He tried to get up, but he was not able to sit or make any movement at all. He was frightened and surprised that he could not move. When he turned his head, he saw that his hands and legs were tied firm to thin sticks on each side and attached to some clips on the ground. His long and bushy hair was also tied down. He felt that there was some movement on his body, near his chin. He was surprised to see very tiny human beings who were less than six inches in height. They had bows, arrows and a case for holding it, at their back.

Gulliver found out later that they were called Lilliputians. Shocked on seeing these tiny people, Gulliver shouted and somehow got his left arm freed from their clutches. The Lilliputians got frightened by his screams, and in defence, they started shooting small arrows into Gulliver's hands, face and body, until he quietened down. The tiny people built a stage which was about 1.5 feet tall near Gulliver. An important person from their island stood on the stage and spoke to Gulliver for 10 minutes in their language. Gulliver did not understand a single word.
