I have had a few encounters, all extremely terrifying and in no way comforting. No light at the tunnel. No peaceful revalations. Just the sensation you are drifting into nothingness

Very comforting.

The first time was an NDE, but I didn't come to close to physically dieing. I was under the influence of 24mg of 2c-e and decided it be a grand idea to take a large dose of 5-meo-dmt. Either I was hallucinating that there was 25mg of 5-meo-dmt weighed on the scale or it was broken (which it was). I sniffed what was probably 80mg of 5-meo-dmt and about 5 seconds in I knew things were going straight to hell, so I run out of my room and down the hall to my brother. All while screaming I'm dying!!! I'm dying!!!. I can't put the experience in words, but as soon as I sniffed that, there was this coldness that sept through my body. Like ice filling my veins. There was this immense rushing sensation like something was weighing me down (largest body load ever).
I felt my soul/concioussness/spirit or whatever, start to disintegrate, as I'm using every bit of strength to grasp anything related to reality it just got worst and worst. The most intense of fears set in, panic, I've never been this frightened in my life. I did't know humans had the capacity for such suffering and agony. At some point I break through, but have no recollection of it. By the time I reentered my body I was in an ambulance on the way to a hospital.

The next close call was actually close. I had just got an order in for 2c-c, so I decide I'd try a small dose and see where it takes me. Never let someone else weigh your dose, unless you are watching him/her. Anyways, I ingest what I thought was 20mg of 2c-c. Wasn't feeling much 2 hours later, so I re-uped. Big mistake. As soon as I swallowed the next dose, the first one kicked in out of no where. Not good considering my mother and younger brother were around. I remember my lil bro asking to change the channel, so in my attempt I grab the controller, but could not figure out how to work it. It all started kicking in at once. I dropped the controller and nervously went back to my room to try to cool off.... Not happening. I recall getting quite scared at this point, so I ran out to my family and told them I F*ed up again. This is where stuff got messed up. I won't go into all the details, but here are some highlights.
My first physical hallucination is that I ripped my middle figure off (In reality it was a cigarette that ripped), thinking to myself I really did it this time. My mother guided me to my bed. There, I believed I had ripped my cats arm off, as real as can be. I saw nerve endings, blood spilling out and felt the pain of my cat. I'm just talking about the hallucinations, it's what was happening with my mind that was the most terrifying. While all this was going on, I was stuck between the realm of death and rebirth. A continuous cycle which was happening at unimaginable speeds. I recall one point looking over towards my mother, wanting the suffering to end, hoping she would have an answer or remedy. She didn't. She's as lost as I am. Shit! I'm on my own. There was this great resistance I was harnessing. No matter how hard I tried I couldnt let go. I felt this sensation of my soul twisting around and around trying to get out of this, looping constantly.
Did I black out? I feel horrible. I'm still on my bed with my mother beside me. I look over at my mom and shes crying. Apparently I started going into grand mal seizures and my heart almost stopped. Fortunately, my mother is a nurse and even though we happen to be out of benzos or anti-pysch's, she administered some seizure medication and some other meds I'm not aware of. The back of my head felt wet. Upon placing my hand on the back of my head, I felt warm blood. My back of my head is caved in. I think to myself, I must of slammed my head on something when I had a seizure and now my head is caved in. Great, I'm dying all because of this damn drug and if I do happen to make it, I'll be mentally challenged for the rest of my life.
8 hours have passed and I'm still tripping hard. I glance over at my mother only to see knifes being jabbed in and out of her chest as her eyeballs pop out.I think this was one of the last disturbing images I had during the trip. I gradually came down and by 7am, 16 hours later, I was at bass line.
The first incident happen 4 years ago and the second 2 years ago. I feel I've made some progress with the 5-meo-dmt experience, but the 2c overdose was all bad and I don't know if I'll ever be able to fully process that one. I find it quite unnerving that both NDE's I've experienced were downright some of the worst experiences in my life. I thought dying was suppose to be peaceful or enlightening...... I dunno, but from my experience dying, it's horrid. I recommend staying alive.

In a separate incident, I fell out from a heroin overdose. As soon as I pulled the needle out I knew I'd done too much and started falling in and out of consciousness. At one point my breathing stopped, but fortunately my friends were able to revive me. Don't remember a thing, except taking the shot and waking back up. Checking out this way would probably relatively peaceful.
Thus far, I'm not impressed with dying.
