I'm trying to survive in the Halo world, plz help....

My name's Robert, Robert Petrov, I died cause of a heart attack. Although, the questions now on why I'm mentioning this as I talk to myself, how the heck can I talk much less think if I'm dead? Well the truth is, I am completely panicking right now!

I had woken up in pain, I was laying on the floor on cold metal, and I was wearing what looked like military gear.

I had a heart attack, I thought I was done for, but the heck is going on, what am I wearing? I looked around, and noticed a transparent looking wall of energy as well as multiple people in cells like mine.

It reminded me of Halo, and in one of the cells I saw what looked like captain Keyes. He was standing there, and as I was playing halo a few minutes ago trying to get legendary completion on my desktop for all of the games, I couldn't help but think, what the heck am I dreaming???

I was so confused, but I felt pain, and I looked down to see a gash on my armor...wait, pain? The mere thought of it gave me goosebumps.

I realized it, I isekaid, sounds nice, I should be happy, but I'm in one of the worst worlds to be in.... I was full blown panicking, I yelled out, "Holy, Jesus, how, why here!!"

"Calm Down Marine", ordered Captain Keyes

I looked at him from my cell, I could hear the battle as Master Chief killed the covenant to save Captain Keyes.

"Sir, with all due respect, I just realized something awful that's going to happen soon, and I'm not talking about these covenant fools!!", I know I can get shot for yelling at the captain in time of war, but I really am panicking.

This isn't something I can just ignore, our entire group with exception of 3 people are absolutely fucked! I'm on a covenant ship in the first fucking game. the other Marines are looking at me, and one of em I hear call me loco, I'm spanish too you asshole!

I'm panicking so much, I can't breath, even if we don't just die normally during the war, we get infected, and become monstrosities that infect us through our nervous system, very fucking painful way to go!!

I'm panicking so much I can't, it hurts, my chest! I collapse to the ground, the pain in my chest hurts so much.

Captain Keyes looks at me in shock, I can see the confusion as Master Chief kills the last elite. "Take deep breaths, calm yourself, master chief open up the cells, and help him", says Cpt. Keyes.

Master Chief shuts down the energy cells, while I try to fight the pain, I take deep breaths, I somehow manage to calm down, when Cortana asks me, "what did you realize?".

When she asks that, I know I can't tell them this is a game, but I have to tell them what's going to happen, if there's a chance to change things I have to take it. As I'm thinking this, I get flustered, I start to take deep breaths again as I feel heart palpitations.

"Ma'am, I had visions when we got here, I know I sound crazy, but these visions came to me ever since we landed on this ring world. I thought I was tired, and ignored them, but as we were captured, things have been going exactly as these visions showed me." I say that as they look at me strangely.

I desperately hope they believe me as tears stream down my face, I really hope they believe me. Halo is a terrifying world, I really don't want to die again, plz believe me.

Master Chief looks at Cpt. Keyes, as he looks at me like I've gone insane. "say we believe you, what are these visions?", Cortana asks me. I take a deep breath, and say, "Ma'am these visions gave me information, it let me understand things, it might be some advanced technology that I was lucky enough to tap into, I don't know, but this ring world is a weapon designed to work with other ring worlds in the galaxy to wipe out organic life as a last countermeasure against a parasitic species known as the flood."

They look at me in shock as I continue, "The covenant here are blinded by their zealotry, and are going to open up a closed off location that contains remnants of the flood that survived the purge. These things infect you through your nervous system, they then convert your biomass into one of their abominations, in order to build something known as a grave mind. It's a hive mind, something that's really powerful, and intelligent to take the memories of the infected hosts to assimilate the tech, and spread to the rest of the galaxy. all of us with exception of you, master chief, and sergeant major Johnson who escapes on his own, will die by either the covenant, or by the flood."

They look at me as I've gone insane, but I continue before they can stop me, "when you escape, you had taken Cpt Keyes implants after mercy killing him later on as he was being turned into a grave mind. You take a banshee to the pillar of autumn, and have the ship start to overload, then taking a bomber back into space as the ring starts to break apart from the explosion. All of this transpires as you also meet a machine called the Guilty Spark who tries to get you to fire the ring.". I look at them....
