Firstly, I totally agree with you skinwalker. I had very similar experiances, not hell per se but definetly things and encounters that were manevolent to the nth degree and beyond what we can understand or rationalize away.
I don't get it, most of you are not even trying to learn from what this guy has been through or is saying, instead you are arguing and trying to make this guy leave the forum. This forum is designed to discuss all matters, not just the positive but also the negative, thats what a forum is for. Close mindedness or getting rubbed the wrong way because you are hearing the negative side of your favourite 'drug' is just immature. Someone who as been and seen the dangerous side to DMT and is warning people should be heard.
Shamans, Buddha Masters with supernatural abilities and other saints and holy people know this is all the real deal, there are uncountable deeper dimensions that exist parallel to our own including various underworlds, manevolent beings more powerful,cunning and intelligent then ourselves exis, spirit possesion is real and yes, this can effect you on this plane when you get back. The ancients knew all this, we in the industrialised paper thin scientific paradigm have forgotten it.
Pablo Amaringo, a famous Shaman most famous for that book he wrote with all those colorful pictures and descriptions of ayahuasca journeys quit Shamanism when a 'helper spirit' turned on him journing a Aya experiance. Another person over at the Ayahuasca forums who thought he was an 'urban shaman' developed schizophrenia after continually using Aya and DMT, he started encountering entities that eventually got full access inside him. Since that time he continually had voices in his head even when he was stone cold sober.
Then there was another guy named Kevin Furnas, he had been dabbling with Aya and DMT for a long time and thought himself somewhat of a Shaman. He got so wrapped up in the whole thing he commited suicide a few years ago as the entities convinced him that if he killed himself he could join them forever.
All these chemicals open the gates of your soul and greater being to the boundless multiverse and it's entities. You are doing this in a totally uncontrolled, clumsy and dangerous manner that can have serious and damaging effects upon your spiritual self.
All serious schools of cultivation of the Spiritual self know that you are on this plane of existence for a reason and that there are no free lunches or shortcuts when it comes to spiritual development. Ask yourself why you are here instead of these liberated multidimensional realms already? Theres a reason you are in this dense realm and not in these places and paying off your debts or Karma/Sins is one of them.
What one is doing when he/she takes DMT or most any psychedelic is that you are short circuiting/hacking your spiritual architecture and entering places that are most definitely real but that you haven't truly earned through your own development in this realm. It's cheating on the 'exam' so to speak.
The truly dangerous part comes into play in that where you end up is utterly random. Shamans use various techniques and tools like rattles and icaros to traverse these dimensions and to protect themselves, even so, they are not totally protected or safe when they journey through these realms. Also, so called 'healing' shaminism is actually still dealing with manevolent entities that have been 'reigned in' so to speak under the Shaman's will:
There is a theme woven through the shamanisms of the Upper Amazon — that human beings in general, and shamans in particular, have powerful urges to harm other humans. The difference between a healer and a sorcerer is that the former is able to bring these urges under control, while the latter...

And here most people don't even want to know of all this and will smoke and think that there 'bad trips' are just that. There is so much more to it then that and so much going on to your spiritual self when you let down your spiritual firewall.
