Real or Not?

Deep inside, the storm it brews        
Unlike one you ever knew          
The swelling darkness, it consumes          
The time is near, the shadows loom          
          
I do not know your darkness          
And you do not know mine          
I wonder who's is greater?          
Perhaps we'll find out in time          
         
What do you do with yours?          
Keep it bottled up of course          
Sworn to never let it out          
Become a beast worth writing about          
         
Can you fathom the depths?          
Wish I could see into your thoughts          
Wonder if visions of death          
The stench, decay and rot          
Echo in your mind like a room full of laughter          
When you look overhead, are bodies swinging from the rafters?          
       
- - -      
         
Don't tell me it's all in my mind          
I can see them right there          
Aren't you listening?          
Can't you hear what I'm saying?          
There's corpses up above          
Beneath our feet and in the walls          
Your words aren't making any sense          
Are you messing with me?          
       
- - -      
         
...Oh, I was just kidding, no need to worry      
Even though I feel a little light headed and my vision's a bit blurry      
I think I need to head to the nearest restroom, I'm rushing      
Before I trip over an unidentified object and get a concussion      
     
When I come to, there's a body lying right across the hall      
With gashes all over, puddle of blood from wall to wall      
It's okay, I guess I'm just seeing things again      
Think I'd better go get this wound cleaned up on my head      
     
A couple of friends come around the corner and scream      
I say I'm okay, just a little dizzy but there's nothing happening      
You can't see it right? There's nothing on the floor?      
Exchanging glances, "Blood", they say, backing away, before      
Pulling out their phones and dialing, saying they'll get me help      
I say, really, I'm okay, I just hit my head on the shelf      
     
When I see the ambulance arrive
I walk outside with arms out wide
I'm the one who's injured, see my head? I need a ride      
I don't really want to pay for it, but my insurance isn't great      
I guess since I'm not fit to drive I'll accept it as fate      
     
Then the cops pull up, screaming to get on the ground      
Weapons drawn, I know that they aren't messing around      
     
Officers, what's wrong?      
I didn't do anything      
I was just headed to the hospital...      
Are you coming along?    
   
Wait, let me just check my phone    
I got a message, don't shoot, I'm prone    
I reach into my pocket and start to pull it out    
        That's when they fire away, there's my life down the waterspout
