The Backrooms Explorers: No Way Out

Part 0. The Frontrooms.

I wake up, shivering. Sweating cold, lost for thought and speech, I can't quite comprehend what just happened, wether if it was real or just a dream. I decide to call my friends to check up on them and see if they're fine. At the top of my contact list, there are two pinned contacts :
Eliza and Podróba. Eliza is an English 19 year-old girl, she's about 175 cm, she has brown hair, she is possibly the nicest out of us all, and very well mannered, her sense of humour is just as stupid as ours, she's most commonly seen wearing colourful flower dresses. Podróba is a Polish, 21 year-old, male giant, he's about 196 cm and  an idiot, like me, he has brown, short hair, wears glasses and most commonly seen wearing military camo clothing. I should probably clarify, they're together, they've been together for about 5-6 years, nearly as much as I've been single. I'm a Venezuelan male who just turned 20 years-old, about 190 cm, I too have brown hair, short but curly, I got a couple scars from fights, I'm seen most commonly in suits and formal clothing, and while I've been single for a while, I maybe finally found someone, but it's unsure. They're both my most close friends, we've been through hell and back together, we're an inseparable trio.

I decided to call Eliza first and after the second ring she picks up, however it's not her voice on the phone, it's Podróba's and he says in a low, tired voice, as if he just woke up.
"Yo dude, I spent the night over at Eliza's, I never grab her phone but I saw you were calling and you would have woken her up. Anyways man how's it going?"
And I answer In my usual energetic voice
"I'm actually really good but pretty weirded out, I had a really weird dream and it left a weird feeling on me, I dreamt that I was being chased by something, I ran through rooms? Like the back rooms of a old retail store, but they stretched on for kilometres!!! I have a feeling you and Eliza were in my dream and I called to see if you guys had a weird dream too?" Podróba goes quiet for a few seconds then he speaks again, this time quicker and if he was scared of something "U-Uh yeah I did, and it's more or less what you described but on a different perspective y'know? I was looking at you being chased... I couldn't do anything, i'm sorry dude, you know it wouldn't be like that."
I tell him it's fine and that he doesn't need to worry about it, he cuts me off to say "Oh dude, Eliza is waking up, listen man I'll ask her about the dream and we'll call you later alright?" I quickly answer "For sure! Don't worry about it, I'll talk to you guys later" and so, I hung up.

I fell backwards into my mattress and stared at the ceiling for a while, shut my eyes to rest them, but they felt so heavy, so I decided to keep them closed and fell asleep.
