Welcome to the Nexus!

It is my understanding that you could safely smoke or ingest DMT orally by yourself or with a non-experienced (but informed) sitter without needing an expert for guidance during the experience.  Check the health and safety section in the wiki if you didnt yet, there's a LOT of good info there, as well as the FAQ. Start with low doses and work your way up.

Also, a meeting that you arranged over the internet to get together with some unknown person to ingest illegal substances is a liability for yourself, for the person meeting you, and for the whole community (imagine the news: "internet forum used to set up meetings for ingesting dangerous hallucinogen drugs"), which could lead into legal problems for yourself and for The Traveler. This is why we do not want people to arrange meeting others openly as you did.. I hope you understand.

By the way, wanting to see more of the iceberg is perfectly fine, but the problem is that the iceberg is no static object to be discovered, it is ever-changing and goes deeper than one can possibly comprehend regardless of amount of trips, so do expect more questions than answers

Be well!
