A "death" dose could possibly be made if it took the brain into the sleep/dream patterns. When you sleep small amounts of DMT are released. When you die, larger amounts are released. That's what causes the "light at the end of the tunnel" and other things people see when they have near-death experiences.
I would love to see a death dose. Just to be able to experience something close to death, obviously without actually dieing. Also, fear would be a good one.
If you really want to walk to death and back, smoke some DMT. Or IM Ketamine. DMT is the chemical released when you dream and while you're dying and Ketamine is a dissociative well known for inducing near-death experience. No, you don't ACTUALLY almost die with Ketamine, it's just that you mind is so disconnected from your body, it feels like you're dying.
wonder what would happen if you recorded the brainwaves of a dieing (ok how do you spell that word) person until they died. Then you make a binaural beat with a base tone of say 200Hz, and then fluctuate the second tone by the main frequency of the recording.
In essence you are creating a binaural beat which, if the listener's brainwaves can adapt fast enough, should give you the same brainwaves as the dieing person.
I think that'd be real cool to go in and out of death at will. Like walking back and forth across a thin line going into and out of a death state. Hallucinate and see Angels and Devils or experience different death experiences. That'd be crazy/
Actually, if they made a really intense dose (more than black sunshine), and started off as a really high brainwave and went lower and lower over an hour long period, then reached zero, it could probably bring you very close to death. Maybe you might actually die. Who knows?
