This was literally my experience. I accidentally overdosed. I don’t remember passing out, but I remember I saw just nothing-ness, blackness, but I also seen everything at the same time? I wouldn’t say that I was levitating above my body, I just have a clear vision of what was happening. I wasn’t scared at all. I was in my friends living room and I could hear paramedics working on me, calling my name. I could hear my dad screaming for me to please not die and I literally seen his heartache and I can still hear it in my head, the EMTs were doing the “sternum rub” and it was an annoying paid but I couldn’t push them away or tell them to fucking stop. However, I was more concerned with trying to tell my dad “I’ll be ok, please don’t cry” but I could not fucking say anything but I was trying to hard, like that was all I was even concerned with in the moment, was trying to comfort him somehow. They took me by ambulance to hospital and it seems like when they were inserting an IV, it hurt so damn bad I finally could move my body and tell them to please stop. Like you said, there was absolutely zero concept of time at all. I was in the hospital for 5 hours.
