It wasn't a calm night. You tried to climb the tree, but you didn't know how - it wasn't a skill you could learn staying in the hospital.
You could hear some mysterious noises all around you that didn't let you sleep a wink.
Unfortunately, within a short time, the noises became closer and you realised these are crocodiles who make it.
There were three of them - you had no way of escaping and surviving this... They attacked you and you can guess what happened next.
You didn't manage to survive in the Universe.
