Where am I?

In a remote corner of unknown continent of unknown world, there was lush forest in the middle of nowhere. At the edges of this forest, on the cliff, hidden passage could be seen. If one goes through the passage, one can see abandoned place that looked like laboratory, pretty shady at that.

Laboratory seemed to be completely cleared from any type of equipment, underground complex had many rooms for different purposes almost all empty, but most eye catching thing was huge piles of lifeless bodies. Bodies were different types: beast, insectoid and also 'humanoid' types, but judging by how different they all looked, it was clear that there were many different species in a mix, some had grey skin, some red, some had multiple eyes, some had tail and horns.

In one of such pile of bodies strange movement happened. One humanoid body started to twitch and after bit of more movement owner of body slowly opened their eyes.

"Ohhhhh bloody hell!! My head hurts" - Said owner of body with deep voice.

'Hmm weird, why does my voice seem different? Don't tell me I drank that much last night! And why the hell I can't seem to remember what happened to me?'

"Well if I think a bit Where am I?"

After looking around and seeing piles of lifeless bodies, owner of voice froze.

'The hell? Where in the world am I? Okay think Sandro think! How can you wake up in this weird place? Why don't you remember coming here? Aaand for the love of god why is my voice different?'

Immediately after small panic Sandro tried to calm himself down, observe the surroundings better and think as rationally as he could.

'Okay now that I had a better look, all those bodies look unusual. I mean horns?? pinkish skin?? wtf? Maybe they are some kind of mannequins? let me check'

He lifted his hand with some difficulty - 'Hmm my hand seems bigger than I remember' - he thought and touched body of seemingly female figure laying near him.

"It's cold and texture of skin seems realistic, too realistic" - Sandro muttered quietly.

After moment he jumped in fright, well at least he tried. He fell to the ground and immediately tried to sit up, with face as pale as ghost. 'Holy bloody, gory hell what is this, why does it feel so real? No no no this can't be! Maybe it's dream?' - after this thought Sandro balled a fist and punched himself in the face.

"Aouch! That hurt, but I still see bodies.." - even after all this pain, he still wasn't awake.

'Sooo... Is this real?' - Sandro thought and took better look at his body - 'Okay, judging by how awkward I feel moving and fact that I'm naked... Did I reincarnated or something?' - Thinking that, he became a bit excited and who wouldn't?

'But wait a minute. If I reincarnated into this body, then does this mean I died? But I don't remember dying and how could I die?' - He furrowed his brows, pondering, but no matter how much he thought about it, he couldn't answer those questions.

"Okay it is what it is, I should get going" - said Sandro and slowly started to get on his feet and move.

After few awkward tries he managed to walk slowly.

'Looks like I'm lot taller than before.' - He looked at bodies and after calculating approximate average height he seemed over two meters tall. - 'Hah, At least now I'm taller than you brother!' - Sandro couldn't help but think about his little brother.

'... Haaah I hope you are okay, wherever you are.' - He thought and sad expression painted his face.

'Well, I must focus on situation here and try to find a way to get out.' - after thinking this he started to walk towards the exit.

'I can more or less see like it's just dimly lit room, but I can't see any source of light. hmm maybe I have night vision? not bad not bad at all. Now let's see if my hearing is also greatly enhanced' - Sandro slowly walked in the direction of door, while remaining vigilant and making as little noise as he could. He arrived in front of door and placed his ear on it. After few minutes of not hearing anything other than noise of water droplets hitting the floor, he tried to open the door. Unfortunately door seemed locked from outside.

'Why would anyone lock the door? It's not like dead bodies could just come back to life and...' - Sandro paused a bit - 'Fine, fine, but I should be very very and again very rare occurrence!' - He justified his thought process - 'At least I hope so!' - He added - 'Anyway what should I do? Door seems quite sturdy, I don't think brute force can open it.' - Sandro looked around to see if there was any alternative exit, but couldn't notice anything.

"Well, brute force it is" - And after walking few steps back he got ready to charge at the door - 'If I'm lucky I might open it in a few charges' - He thought and started his charge.

In those few minutes while he was walking around the room his control over body improved considerably and now Sandro managed to run somewhat fast. After gaining a momentum he pushed ground with feet and jumped almost horizontally towards door.

Bang

With loud bang Sandro hit the door with his shoulder and to his surprise door got blasted open. Unable to stop his momentum he hit the floor of hallway and sound of metal hitting the stone echoed in lab complex.

'Damn it!' - Sandro screamed in his head and carefully looked around, perking up his ears to hear if anyone was coming.

After listening surroundings and not hearing anything, he relaxed a bit.

'Looks like this place is deserted and door fell this easily because it had gained a bit rust' - He thought this not realizing that in that case bodies would have been rotten already.

'I guess by exploring I will get a bit more info about this place.' - Sandro thought and got up from ground and started walking down to hallway.

After few dozen minutes of exploration, he concluded few things:

First, this place looked like underground lab, it was empty, with no lab equipment or anything like that.

Second, It seems that it was recently abandoned, how did he understand this? Simple, there was layer of dust, but not too much.

Third, whatever experiments being made here wasn't exactly ethical, as if room full of piles of dead bodies wasn't enough, he also found some broken cylindrical tubes made of glass like material, judging by creepy cyan liquid and remains of dried blood, he concluded that those 'test subjects' were already destroyed.

After walking around some more and not finding anything, not even some clothes, he stopped what appeared to be central lobby of lab complex and exclaimed loudly.

"Seriously, Where am I?"
