Pain. That's all he felt. Pain, emotional and physical, but nonetheless, pain.

Danny had just escaped from three years of torture provided by the Guys in White, most commonly known as the GIW.

His parents had found out about his powers and who he is, but they didn't care what 'it' had to say. Truth is, Danny is half ghost, half human, he has been like this since he was fourteen. His parents were ghost hunters, they despised ghosts and thought of them as scum, as monsters that couldn't feel, so, they spent their lives trying to find ways to stop them, and one was to create a ghost portal. It opened a space between our world and theirs, but, when they turned it on, it didn't work. Danny was dared by his best friends, Sam and Tucker to go in, so he put on a jumpsuit and did as he was told, he was exploring and accidentally tripped on some wires, he hit an on switch. Excruciating pain rippled through his body, his molecules merged with ectoplasm, he now has a ghost half and a human half.

The town of Amity had different views of the ghost boy, whether he is there to save the town or destroy it.

Anyway, his parents brought him to the GIW and let them experiment on him, to Danny the torture was worse than the lab accident, and now, he has escaped.

Danny was still in his ghost form, he healed quicker that way, he was stumbling through a forest, looking for a place to rest. He found a tree that was thick and tall, he climbed it and slept there for the rest of the night.
