A/N This is my first story. I apologize for any mistakes and I hope you like it!
"Where d'you want to go next?"
"I don't know. A vacation would be nice, you know, sometimes you gotta take a break from the monsters," Donna said while walking around the console.
"Okay doke then." The Doctor pressed a few buttons and when the TARDIS landed, he looked at Donna with a smirk on his face. "We can be anywhere right now. We can be on a resort planet, like Midnight, or well, I could've pressed a wrong button."
"Oi! Spaceman! Stop it! Let's just open the door and I hope it's a resort planet!" Donna ran to the door and opened it widely.
The first thing she felt was the smell of a forest. The clean air filled her lungs and suddenly a feeling of calmness came over her. She stepped out of the TARDIS and looked around. They were indeed in a forest. The pine trees were surrounding them and the forest seemed endless.
"Where are we?" Donna asked when the Doctor came out of the TARDIS. "Are we on Earth?"
"No, I don't think so. And there's a chance I might have pressed the wrong button. Oh well, this place looks nice. We can make a picnic and look around. What do you say?" the Doctor suggested and Donna nodded. They headed through the trees, leaving the TARDIS behind them.
As they walked they could hear a nearby stream murmuring and birds singing. After ten minutes of walking, Donna suddenly stopped. She opened her mouth to say something but then she changed her mind and closed it.
"What's wrong?" the Doctor asked.
Donna hesitated but answered, "The birds… It's like they are singing the same tune over and over again, it doesn't sound natural! It's weird."
"I haven't noticed that," the Doctor said looking a bit confused. "Are you sure? I would have heard it by now. They are just ordinary birds."
"Probably, yeah, I suppose you're right," Donna agreed and they continued their walk.
During the next few minutes the Doctor gradually started walking slower, his breathing became troubled until he finally leant against a tree.
"You alright?" Concerned, Donna approached him.
"I'm fine, I just got a little tired, that's all. Do you want to sit down for a bit?" And as he was saying that, the Doctor sat under the tree, leaning against it, and closed his eyes.
"You never want to sit down for a bit. What's happening, Doctor?" Donna insisted and sat on the ground beside him.
"Nothing, Donna! I haven't slept in a few days, so that's probably it. Nothing to worry about," the Doctor assured her and buried his face in his hands, but she still wasn't convinced enough and looked at him worriedly. "We'll just sit around here for a while and then we'll continue our walk and try to figure out where we are," he faced her and smiled, "Really, don't worry. I'm fine."
"Okay." Donna smiled back and gazed at the forest.
The forest calmed her. It almost looked like as if it were magical; it made her feel strange, but a good strange, like everything was enchanted. The noises, the chirping, the clicking, the twittering, they were just so lulling. The grass they were sitting on was soft and green, even greener than usual and the trees were majestic, all so tall and strong and… didn't they look a bit too similar to each other? Donna closed her eyes for a couple of seconds and then opened them again. No, this time she was sure that something was off.
"Okay, something is not right! Look at the trees. How can all of them have the absolute same branch at the exact same spot?" Donna exclaimed, pointing at the trees, "That just doesn't happen! And I wasn't wrong about the birds! Don't you hear them? It's the same repetitive melody, it's been going on since we came here! I'm telling you, Doctor, this place is odd! Maybe it's because we are on a different planet but still… What do you think?" Donna stopped to take a breath, "Doctor, what do you think? Doctor? Doctor!"
Donna turned around to see him and gasped when she saw him lying on the ground, unconscious.
