Caterpillar

At the first look it seemed a normal caterpillar, it was bright green with black and red spots, and very tiny. Rosamund stared at it as it moved through the leaves of her lilies, she wouldn't have spotted it hadn't it been because it moved. She hadn't seen anything like it again, and wondered which kind of butterfly would it become. Curiosity was stronger than the fear than it could be potentially poisonous and she looked closer, her eyes at the same level of the strange caterpillar. It was very fluffy, probably half of it's volume was this very thin hair. Rosamund had to touch it, even if she ended up with a rash. That caterpillar was possibly the fluffiest thing in the universe and she wouldn't die without having touched it. 

It was like touching a cloud. The caterpillar stopped moving for a second, but it fastly climbed on her hand. It seemed curious about the new surface. Rosamund let it do, thinking about putting it back on the leaves afterwards. Before she knew it, the caterpillar took a plunge and penetrated her skin as if it had been a liquid surface. She freaked out adn ran to the hospital. In the emergency room no one believed her, there was no entry point and the tests they ran didn't show any abnormal body inside of her. Yet, she could feel it, moving swiftly under her skin, up to her arm and into her brain. 

Rosamund spent the following two days going to the emergency unit trying to find someone to help her, but it was clear no one believed her, caterpillar don't enter into human bodies. After two days the caterpillar had finally found a cozy spot in Rosamund brain where it would spend the rest of his days. At that same time she started behaving in a different way. She had always been an extroverted person, who had lots of friends and would throw parties. Rosamund loved hosting parties. She became a silent person who stayed alone most of the time. Her friends started worrying about her, but she shoot them out. 

Rosamund's mother, worried about the strange behavior of her daughter decided to pay her a visit. She found that plants had taken control of the house as they were everywhere. Her daughter was in the kitchen eating a salad of what seemed to be random leaves picked from the garden. 

-Rosie, are you ok? 

-Ugh, yes, mother. Leave me alone.- she mumbled while chewing on the leaves. 

Her mother tried to get something else out of her, but she wouldn't answer, focused on slowly chewing the leaves. Rosamund mother's mood wasn't soothed at all, and she decided to find some help for her daughter, who was clearly having some kind of mental breakdown. 

The psychiatrist, an old friend of Rosamund's mother, went to Rosamund's house two days after her mother's visit. He rang the doorbell, but there was no answer, he circled the house from the outside, trying to see if Rosamund was home, but there seemed to be no one. What there was was a very large cocoon in the middle of the garden. He wondered what it was for as it clearly wasn't something produced by an animal. Giving up, he called Rosamund's mother and told her that he hadn't found his daughter. 

Rosamund was reported as missing two days after, and was never seen again. The large cocoon remained in her garden until it rooted over as whatever was inside of it wasn't unable to complete its metamorphosis.
