TIFU by drinking copious amounts of coffee and feeling it's consequences as I went to sleep right away

This TIFU occurred a few minutes ago so bear with me if I write some bullshit as I'm still sleepy. So..... About me, I'm 17m. I am writing this as I have just woken up a few minutes ago. English isn't my first language so please forgive me if I make mistakes. So, this is how things went........

About 3-4 hours ago, I was extremely tired and sleepy but I had to study as I had some topics left to do. I already had a minor headache and some body pain but it wasn't really bad. So, naturally I decided to have some black coffee to stay awake. I don't remember how much I drank, but from my experience, I'd say about 350-400mg, judging by the size. As soon as I drank the coffee, for the first 15min I studied normally, but was later advised by my cousin to sleep as we had planned for a trip the next day.

I didn't give much thought and lay down as I didn't want to ruin any plans. I forced myself to sleep. Trust me, it was hard, but I slept. Well..... the thing is, after I had slept I had this weird-ass hyper detailed dream that I'm still thinking about right now. I still remember all of it. Lemme just talk about this dream real quick.

For some reason, in the dream, I'm in a village and there's a power cut. I'm at my cousin's place but it's just us two and her mother. As there's a powercut, we decide to just sit on a bench which was conveniently in front of the house. We sit there for a few minutes and wait for the power to come back so we can go back home (why tf would we come out of the house if there's a power cut? Well... I think it was because we couldn't see shit in the night lol.) So... her mother just left somewhere and we were just sitting there chilling. A while later, an old lady comes and sits beside our bench with this abnormally huge crab that was about half my size. She seemed creepy to me, but we still ended up accepting her to stay as there was a power outage. Whenever I looked at her face, it always seemed distorted and she would always stare back with an eerily creepy smile. I don't remember a portion after this but I'll continue from the next part which I remember. So.... as far as I remember, she's sleeping on a bed in the house and I stab her on the neck with a knife. She dies having several convulsions but it's a quick death. Her pet crab notices this( It wasn't really a pet, more like a son to her.).

Well... I kill her and like a video game boss he wakes up and immediately tries attacking me. I can't express how horrified I was, I almost pissed myself, That thing is fucking half my size, ahhh. But there was this sense of regret that I felt after I killed her, It seemed... almost too real. I could feel my heart beat faster and I genuinely felt bad for the crab. A motherless crab who just lost the only thing he had for him. I thought to myself, the other people will think of him as a freak, his mother was the only one who treated him as a son. I don't think words can express how regretful I was. It felt like I had killed a real human being and was regretful of my actions.

But here's the worst part, the crab son wants to take revenge and kill me now. Ok, a bit of spoilers, I kill that mf too, but bear with me when I say I kill him in the most gruesome and disgusting way and it's so baaaaad.... like... ugh!! Well....... Lemme just continue lmao. So he's attacking me now. What should I do? What should I do? What should I do? What should I do? What should I do? What should I do? That's exactly how I heard it in my mind with overlapping voices, kinda like a movie.But it was so intense that I was literally panicking. So I grabbed the knife and stabbed his hard body, only for the knife to bend and slip out of my hand. I was backing out as all of this was happening. I hit a wall, I don't know what to do!! Am I stuck?? Nah, there's gotta be some way out of this.

I see a table, I run under it and come from the other side, the crab tries to do the same but is somehow stuck under it. I take this opportunity to strike when I have my chance. I grab my belt and skillfully fasten one of his arms with it. I use one of the legs of the table as a lever and pull as hard as I could. As the crab's body is too wide to pass through the table, he's still stuck there. I yank hard and his left arm just takes off and some of it's contents spill out. The arm has been amputated. The crab cannot talk, but it screetches and I can hear him scream in pain. He holds his other hand in front of the broken one to stop the bleeding. (I don't know if crabs bleed irl, but that's what I remember from the dream. Damn, I even forgot I was talking about my dream, I thought I was story-telling lmao.)

So.... the crab's in pain but I can see the fire of revenge in his eyes burn brighter than ever before. He cuts off the two legs of the table near him so that the table falls like a slope and he rushed towards me. This time I ran towards my cousin's room hoping for some assistance. I picked up my knife from earlier and continued running. I run as fast as I can but I don't seem to be getting anywhere, the crab's approaching me, how can I get through this predicament?? I have to think fast but it's too late now, I have to just fight him, there's no other way. I grab the knife with both of my hands and aim for his eyes this time. With a stab from the side, I get both of his eyes. He's completely blind, I've won. It's over now!! It's over now, right? Right.....

Well, the crab goes berserk, he spins around randomly and just cuts everything in its path with full force. It's like he doesn't even feel anything anymore. He doesn't care if he's dead, he just wants me to die. He only has one aim in his mind, and that is to kill me. The knife inside his eyes just flies off as he spins. He's still blind but we're in a narrow passage in the house so the only way towards me is a straight line. My cousin's room is on the other end of the narrow passage. He somehow walks in the right direction. It's as if God wants him to win. I run towards my cousin's room and actually succeed this time. The crab follows me!!

I wake my cousin up and tell her everything. The crab finally reaches us. Haha, we've got a plan this time tho. My cousin is standing beside him, he doesn't know that yet. She pushes a bookshelf which lands directly on him, he's unable to move now. But due to whatever fucking plot-armor, this mf just lifts up the bookshelf on it's back and slowly walks in my direction. God was playing his favourites that day, I guess. Well.... my cousin is a quick thinker, she lays down on top of the table which makes the crab unable to move. She tells me to end that little fucker once and for all as that's the only way. He's unable to move, but he grunts with all of his might, trying to lift the bookshelf again and falling down every time. I walk over to him. He's still swaying his one arm in random directions, trying to get me. I feel the remorse. He did nothing wrong, it's all my fault. I killed his mother and he just avenged her death. I cut off his arm, I blinded him, he's done nothing to suffer all of this. Am I the bad one here??

Well... I still decide to kill him to put him out of his misery. I grab a book and repeatedly hit his head, he starts to shake violently in pain. It's absolutely gruesome and feels wrong. Finally he stops moving, I think that's all he got, he's dead now. But as soon as I stop, with all his might, he goes for one final blow. He swings his arm but juuussst missed me. That shit was so terrifying, almost gave me a heart attack. As a final blow myself, I hit his head with the book one last time and he dies fr this time.

As soon as he dies, I wake up irl lmao. Shit sounds like a movie ngl. I swear to God I was sweating so much as I woke up. I could feel my heart beat abnormally faster. I have a headache with a teeny tiny bit of nausea while writing this, I think I'm gonna go sleep after this. Well... I had never experienced such a realistic dream with such great details that it almost felt real. I'm shaking while typing this as this has just happened. I went to sleep at 00:30 and woke up at 01:57. I think I'll go sleep again. Thanks for reading, Bye : )

Tl;dr: I drank a shit ton of coffee and decided to go sleep. While sleeping I had this abnormally detailed and realistic dream about a crab. We had an epic battle and I bodied that mf in the most gruesome way imaginable. I'm still terrified about it. I woke up sweating and a faster heartbeat. I feel nauseous and have a slight headache. I think Imma go sleep again. Thanks for reading this nonsense. And sorry if I messed up something, I just woke up.
