A farm worker was terrified after waking up to find a king cobra under his bedroom shelves.<br /><br />The lad, named Prasit Pakorn, turned over from his pillow to see the reptile's body with its distinctive dark grey scales on the ground next to him.<br /><br />Prasit, 20, yelled for help from neighbours, who dragged the serpent outside the house in Krabi, southern Thailand. They stretched it out and it measured around 14ft long.<br /><br />Prasit said: ''The cobra must have come into my room while I was sleeping. I'm relieved that it didn't bite me.''<br /><br />The highly venomous king cobra is found throughout southern Thailand, where they live in the dense jungle and feed on lizards and other snakes.<br /><br />However, they are considered a vulnerable species on the (IUCN) Red List of Threatened Species and often venture into villages while searching for food.
